Term Description | |
Active layer The editable and insertable layer in SmartFIB. | |
Adjustment points After loading the specimen to the microscope, the absolute position and the angle | |
between specimen system and stage system are undefined. An Adjustment | |
procedure makes it possible to find out the coordinate transformation from the | |
specimen-system to the stage-system, which allows you to navigate on your | |
specimen by means of specimen coordinate (using for instance the virtual specimen). | |
For this process some points with well known coordinates in the specimen system | |
are needed, they are called adjustment points. Of course the accuracy of the | |
adjustment cannot be better than the accuracy of the used stage. In fact there are a | |
lot of variations for choosing the points and the specimen adjustment tool is aimed | |
at attaining as much information as possible of your chosen set of adjustment points | |
and avoiding overdetermination. | |
Alignment accuracy The alignment accuracy indicates the variation between the actual position and the | |
target position. This procedure is referred to as Alignment process. Approaching the | |
target by means of correcting the beam deflection (digital shift and rotation) | |
according to the mismatch between actual and target position can achieve an | |
accuracy of less than some ten nanometers. | |
Alignment marks For the execution of an Alignment process one needs to take an image which | |
exhibits some structure characteristics with well known coordinates. This can be | |
either specially structured adjusting aids or some distinctive features of the already | |
patterned structures, both are referred to as Alignment marks (or simply marks) here | |
in general. | |
Alignment process It is a common challenge for a lithography task to place new elements in the correct | |
positional arrangement with respect to some already existing structures on a sample. | |
eLitho offers a capable method to execute the positioning procedure which is | |
referred to as Alignment process. The basic steps of an Alignment process and also a | |
lot of additional information concerning this matter can be found in the section: | |
Alignment settings tab. In many cases a single-step Alignment process is sufficient to | |
achieve the required alignment accuracy. In some cases however when a very high | |
accuracy is claimed there is the necessity to execute more than one cycle of the | |
procedure. eLitho allows you to set up these multi-step Alignment processes clearly | |
and gives you the opportunity to configure the procedure adequately for nearly every | |
alignment task occurring. Please do not mix up the Alignment process described here | |
with the sample adjustment, which is used to determine the position and the | |
orientation of the sample system according to the stage system. | |
Area dose The area dose is defined as electric charge per area in micro-Coulomb per square- | |
centimeter: Beside its general meaning as a dose value for exposure (see: Exposure | |
tab) the area dose is also relevant for the image capture during an Alignment process | |
(see: Capture area tab) ). Image capture causes some undesirable background dose | |
within the capture area. Hence it is necessary to incorporate this area dose for the | |
following exposure process. On the one hand the overall background dose must not | |
exceed a certain critical value. For resist processes the capture area ought to be not | |
dissolved by the developer and for beam induced processes the deposition or | |
removal of material should be minimized. The area dose rises with the resolution for | |
a fixed Pixel time. | |
Area element Rectangles, circles, ellipses, arcs, and polygons are normally drawn as (filled) area | |
elements. They are scanned as laminar elements and therefore they are treated with | |
the Area settings made in the eLitho Exposure settings tab. | |
Backlash The backlash feature is a common method to compensate the mechanical tolerance | |
of a mechanical drive gear. The sample stage on a SEM for example implements this | |
feature by always approaching the end point of the stage movement from the same | |
direction of motion. This means that for motion in the opposite direction the stage | |
exceeds the aimed target position by a certain distance (the backlash) and finally | |
approaches the position by moving back with the intended direction of motion. | |
Beam Blanker In order to avoid unintended exposure during standby times and beam settling times, | |
which are necessary after large jumps (e.g. delay between elements, see: Exposure | |
tab) it is recommended that the SEM is equipped with a fast electrostatic Beam | |
Blanker. This devices create an electric field in the microscope column for dumping | |
the beam somewhere in the column. The advantage of an electrostatic blanker with | |
respect to an electromagnetic one is that the beam can be switched on and off very | |
fast. | |
Cycles The cycles determine an amount of identical iterations to achieve the required dose. | |
Prevention of redeposition (deposits of etch/mill waste) during milling or layer-by- | |
layer deposition. | |
Dose The dose determines the cumulative intensity (depth or deposition height) within a | |
patterning element. | |
Dose value The term dose is of crucial meaning for the lithography-process. It is defined as | |
charge per dimension unit and describes in principle the ammount of electrons (or | |
ions) that are hitting the surface of the sample in normalized values. For example | |
when writing area elements applying an positive resist process, the amount of | |
lectrons needed for breaking up enough chemical bonds of the resist in the exposed | |
area to make the resist solvable for the devolopper is given as an area dose in units | |
of charge per area [µC/cm²]. The dose value in this definition does neither take the | |
energy of the electrons into account nor does it include their temporal distributiion. | |
The relevant dose values for an adequate exposure is depending on many | |
parameters, e.g. the resist or the substrate. But of the the most decisive influence for | |
resist processes (at least for some substrates) originates from the Proximity effect, | |
which causes a non-uniform dose-background within the range of some micrometers | |
around exposed regions. Due to the different dimesionality eLitho differntiates | |
between pixel dose, line dose and area dose . | |
Dwell time The dwell time describes how long the charged particle beam remains at one point | |
of the scanning area. The scanning mode, the dose and the spacing influence the | |
dwell time. | |
Element An element represents the lowest level in the hierarchy of a layout. An element can | |
be a single point, a single line, a poly-line, a filled or outlined rectangle, a filled or | |
outlined circle, a filled or outlined ellipse, a filled or outlined arc or a filled or outlined | |
polygon. Each element is assigned to exactly one layer. | |
Exposure Process during which patterning elements are being transferred to the specimen by | |
interaction with the charged particle beam. | |
Exposure parameters To be able to fulfill various process requirements, the exposure parameters describe | |
the temporal and regional sequence of the exposure process. | |
Exposure parameters are settings for controlling the exposure of an entity and | |
comprise settings including doses, dwell times, pixel spacings, and microscope | |
probes. Entity in this context may refer to: graphical elements (lines, rectangles, | |
raster images, etc.), layers (also the implicit live mode layer), or positions. | |
Faraday cup A Faraday cup is a special device for precisely measuring the specimen beam current . | |
The electron beam is dumped into a sink for electrons (cup), which means that as | |
many electrons as possible from the incident primary electron beam are collected | |
thereby producing as little as possible secondary electrons. Thus a measurement of | |
the current from the Faraday cup to the electrical ground reflects the actual beam | |
current which would expose the specimen under similar conditions. The exact | |
knowledge of the specimen beam current is necessary to precisely determine the | |
dwell time for the beam in order to achieve a given dose value. | |
Focus plane This plane matches the unintentional tilt of the sample. It is calculated from several | |
positions where the focus is adjusted correctly (see: Setup of a focus plane). A least | |
mean square fit is used to do this. So, whenever eLitho moves the stage and a focus | |
plane is set up, the focus will be updated according to the focus plane. If you want | |
to use this tool when navigating the stage by means of the Stage tab in the control | |
panel, the Focus tracking feauture must be activated. | |
GIS The Gas Injection System (GIS) is used to support etching processes chemically (by | |
injecting reactive gases) or to provide material for beam induced deposition (by | |
injecting precursor gases). | |
Image mode Working with eLitho covers two different operational modes: the image mode and | |
the sample mode. In image mode some of the menu entries and tools are adapted to | |
the work with the capturing and administration of images. The main difference with | |
respect to sample mode is however, that the working area is used for displaying the | |
images instead of the virtual sample and the structure-assembly. | |
Layer A layer is an abstract definition of a collection of certain properties which can be | |
attributed in the Designer to the elements by assigning the elements to the layer | |
(see: Layer Attributes and Layer Manager ). All the elements of a structuremare that | |
are assinged to the same layer constitute a writing position. The employment of | |
layers is often used to distinguish the different process steps of a sample. This can be | |
on the one hand just a different size of the scanning area and on hte other hand it | |
can be a totally different patterning process (e.g. etching or deposition of material). | |
In some cases it may be also useful to assign the certain elements to a writing | |
position to a seperate layer because they should not be written at all and are used | |
only to assist the design process or for administrative purposes (e.g. id- numbers or | |
background images). Designer offers sophisticated possibilities to display the layers in | |
different coulors, so that it is obvious to recognize to which layers the respective | |
elements are assigned to. | |
Layout Geometric arrangement of patterning elements (e.g. in arrays or other functional | |
units) within scanning areas grouped in process steps and process parameters. This | |
arrangement can be saved in CAD format. Various foreign formats are supported in | |
addition to the native *.ely format. | |
Layout files A Layout-files is the computer file in which a layout is saved. There is a broad variety | |
of different file formats which are used in the field of lithography. Very common files | |
are GDS, GDSII, CIF and DXF or even bitmaps (BMP, TIFF, ...). Although eDraw eLitho | |
are able to support all this mentioned formats, nanonic offers a native file format for | |
layouts which is called eLayout-file. The file extension of the eProcessing-files is *.epr. | |
This format supports hierarchical multi-layer multi structure layouts. Even more it is | |
able to handle lithography specific information such as scanning area dose factors | |
and scanning methods. | |
Line dose Line elements are exposed as a chain of single pixels along the direction of a line. | |
Therefore this "one dimensional" elements are also called "single pixel line". The line | |
dose specifies the electric charge per length unit in pico-Coulomb per centimeter:. | |
Mask layer For alignment processes it is necessary to capture images from the region of interest | |
in order to find characteristic orientation features. Capturing a "normal" image will | |
expose the complete image area to the electron beam. eLitho offers a versatile way | |
to avoid unintentional exposure of especially critical regions within the image frame. | |
This is achieved by allowing to subdivide the image area in regions where the beam | |
is switched on and regions where the beam is switched off during the image | |
capture. The different regions are determined by combining a writing position | |
designed with edraw that contains rectangle elements exclusively with the image | |
frame (see: Alignment tab). Thus the beam is switched on only inside the rectangles | |
and will be blaked outside this areas during the image capture process. The writing | |
positions that are used to screen out certain reagions of the capturing area are called | |
Mask layer. | |
Milling Milling stands for the local removal of surface material by means of the focused ion | |
beam. For instance, you can mill cross sections which allows you to get a 2D view | |
into the specimen. Milling is done by processing individual milling objects. The milling | |
object defines the area to be scanned by the focused ion beam. Milling objects are | |
geometrical patterns such as line, rectangle, and trapezoid. Moverover, several | |
milling parameters such as milling mode, milling current, width, and height | |
characterize a milling object. | |
Orientation grid In the working area as well as in the drawing area it is necessary to position | |
geometrical objects. In order to support this process eLitho and eDraw are offering | |
an adjustable backgrond grid. This grid can be used on the one hand just as a means | |
of orientation or on the other hand when it is switched to "magnetic" it discretizes | |
the positioning area in steps of the grid pacing. See: eLitho Standard toolbar eDraw | |
Standard toolbar. | |
Patterning element Geometric object that shall be transferred to the specimen by means of particle | |
beam processes. | |
Pixel time Every object that is scanned during the lithography process is composed of discrete | |
single pixels. Thus the signal is integrated for every pixel of an image and the | |
elements that are patterned are also composed of discrete pixels. In case of | |
patterning the dwell time (in combination with the spacing of the pixels) determines | |
the dose that is achieved by the exposure. Speaking of the Pixel-time therefore is not | |
only sensible for a point element but also for every scanned object. | |
Pixel dose For Point elements the Dose: is just the electric charge per point in femto-Coulomb | |
Preview The Preview window displays resulting exposure parameters (mixture of entered and | |
calculated) for the current selection. the purpose of this window is to give an | |
overview of current parameter groups and to see if there are any discrepancies. | |
While setting any exposure parameters, the Preview window can remain open. This | |
provides immediate feedback for the selected parameters. This function is especially | |
useful when creating new recipes (one can see immediately, why something is not | |
working). | |
Proximity effect Mainly the secondary electrons are resposnible for the exposure i.e. the cracking of | |
the polymere chains of the resist in an lithography process. Those secondary | |
electrons do not only leave the sample surface exactly at the spot where the incident | |
primary electron beam hits the surface but also a large distance from that spot away. | |
In general the distribution of the secondary electrons leads to a core region around | |
every scanned point (some ten nanometers) where the dose is rather high and a very | |
extensive region where some kind of background dose is deposited. Because of this | |
rather wide ranging (several microns) background exposure the dose at a certain | |
point is also determined by the number of pixels that are exposed in a wider | |
proximity of the very pixel. This effect leads to a nonlocal dependency of the dose | |
within a pattern and can cause massive influence on the resulting dose distribution. | |
This so called Proximity effect often makes it difficult to determine the necessary dose | |
ditribution for complex geometric structures. There are computer programs which | |
can assist the user with this process by simulating the exposure process and | |
calculating the necessary dose distribution using iterative algorithms. In some cases | |
however the Proximity effect effect makes it impossible to expose a geometric | |
structure. | |
Quick navigation For large layouts it is not always easy to navigate in the working area or the drawing | |
area when working at an adequate zoom level. To assist the user in such situations | |
eLitho and eDraw offer the quick navigation tool in the bottom right corner of the | |
respective area on the GUI. Clicking at this symbol opens a small overview window in | |
which you can navigate the displayed area in the working area or the drawing area | |
by means of the mouse by shifitng the non shaded area in the navigation window. | |
The size of the non shaded area is automatically adjusted to the actual zoom level. | |
Sample mode Working with eLitho covers two different operational modes: the sample mode and | |
the image mode. In sample mode some of the menu entries and tools are adapted to | |
the work with the structure-assembly on the virtual sample and the administration of | |
layouts and lithography parameters. The main difference in comparison to image | |
mode is however, that the working area is used for displaying the virtual sample | |
instead of the images. | |
Sample system The sample system is the coordinate system which is used to describe the positions | |
of writing position in native corrdinates of the ideal system of the virtual sample. The | |
unit used in the sample system is micrometers (µm). | |
Scanning area The scanning area describes a quadratic field. The beam can be deflected inside of | |
this field during the writing process or the image capture procedure. The scanning | |
area is defined either in eDraw (individually for each layer) or in eLitho for image | |
capturing (see: Image Capture). It can be shifted and rotated with respect to the | |
standard scan-system of the microscope. The scanning area determines the | |
magnification which is chosen at the microscope. The exact value of the chosen | |
magnification depends on the microscope and if so of the settings of the alignment | |
process. | |
Scanning mode The scanning mode determines the fill pattern during the exposure process. | |
Spacing Spacing determines the step size along the scanning path. | |

The following terms are used in SmartFIB. Understanding these terms gives you a | |
better understanding of the SmartFIB software. | |
Term Description | |
Cycles When milling the cycles determine the number of identical iterations to achieve | |
the required dose. Larger numbers of cycles reduce redeposition. | |
Dose The dose represents the cumulated charge per area unit of a patterning | |

Term Description | |
Preview The Preview window displays the exposure parameters previously entered, | |
along with the remaining parameters calculated from them for the current | |
selection. In particular, the Preview window resolves parameters by considering | |
parameters of different entities. The purpose of this window is to give an | |
overview of current parameter groups and to see if there are any discrepancies. | |
While setting any exposure parameter, the Preview window can remain open. | |
This provides immediate feedback for the selected parameters. This function is | |
especially useful when creating new recipes (e.g. you can see immediately, why | |
a parameter combination is not valid). | |
Scanning area The scanning area describes a quadratic field. The beam can be deflected inside | |
of this field during the writing process or the image capture procedure. It can | |
be shifted and rotated with respect to the standard scan-system of the | |
microscope. The scanning area determines the magnification which is chosen at | |
the microscope. The exact value of the chosen magnification depends on the | |
microscope and if so of the settings of the alignment process. | |
Scanning mode The scanning mode determines the fill pattern during the exposure process. | |

3.2 SmartFIB Program Suite | |
The main purpose of the SmartFIB program suite is to transfer geometric elements | |
to a specimen with the help of a particle beam. This process is referred to as | |
"Exposure". | |
SmartFIBprogram suite consists of two main programs: SmartFIB itself and | |
Designer. | |
Each of these programs has a different field of use. The following bullet points give | |
you an overview of typical applications. | |
SmartFIB | |
Main tool for online/live work on the microscope. | |
Milling/etching/deposition of patterning elements. | |
Provides Sample Mode (mainly used for recurring/automated workflows) and | |
Live Mode (mainly used for circuit editing and creating recipes). | |
Designer (requires the licence CREATOR): | |
Offline creation of layouts (arrangement of elements in the scanning area). | |
Interaction with Sample Mode (used as a drawing tool for Sample Mode). | |

Software Manual SmartFIB | en1.2 | 346000-8083-000 29 | |
An exposure session contains all the necessary information such as various process | |
parameters and a layout. Subsequently, the exposure starts and the process can be | |
monitored and documented. | |
You can create layouts in the Designer and/or in Live Mode based on a | |
microscope image. | |
Layouts can be created hierarchically from multiple layers. During the creation of | |
the layouts, different stage positions and scanning area sizes can already be taken | |
into consideration. Process-specific attributes can be assigned to the layout such as | |
scanning strategy, drift correction and exposure parameters. These attributes can | |
either be assigned on element level to whole layers or to whole positions. | |
Attributes and hierarchy levels of a layout can be saved conveniently and thus | |
enable easy reusability. By creating your own toolbox, this allows you to accelerate | |
recurring workflows. | |
Sample Mode allows you to arrange the created layouts on a graphical | |
representation of a specimen. You can use this arrangement for navigating the real | |
specimen during the exposure and during process validation. | |
You can arrange scanning areas on the specimen either based on coordinates in | |
Sample Mode or by retrieving regions of interest on microscope images acquired | |
in Live Mode. | |
The geometrical elements comprise standard shapes, such as circles, rectangles and | |
polygons, as well as predefined elements created for specific tasks. This includes | |
elements for cross sections and TEM lamellas. The attributes of these elements are | |
already customized for specific tasks. This allows you to completely perform tasks | |
with a small amount of parameters. | |
The microscope controls are fully integrated into all workflows such as creating | |
layouts, as well as during the exposure process. | |
Especially on CrossBeam systems, this allows you to carry out complex processes | |
combining the imaging capabilities of the microscope and the patterning | |
functionalities of SmartFIB. | |

Limited to one scanning area | |
The background image obtained with the charged particle beam serves as | |
orientation | |
Mainly used for | |
Circuit editing or creating recipes | |
Target preparation at a Point Of Interest (POI) / Region Of Interest (ROI) (e.g. | |
TEM-lamella preparation at a specific point of the specimen) | |
Analysis of one specific point of the specimen | |
Sample Mode | |
Allows you to process multiple scanning areas e.g. of different size and to | |
position them on the specimen | |
The focus is on the layout-oriented approach | |
Mainly used for | |
Recurring/automated workflows | |
Combination of different structuring processes: If the specimen has been | |
modified before, there is also information given (e.g. Lithography) | |
CAD layout navigation | |
Documentation of processes and specimens (which steps were carried out? | |
Repeatability) | |
Simulation of complex processes also possible in offline mode | |

3.4 Exposure Parameters | |
3.4.1 Hierarchy of Exposure Parameter Assignment | |
Exposure parameters are settings for controlling the exposure of an entity and | |
comprise settings including doses, dwell times, pixel spacings, and microscope | |
probes. Entity in this context may refer to: | |
graphical elements (lines, circles, polygons, etc.), | |
layers (also the implicit live mode layer), or | |
positions (in Sample Mode). | |
In order to specify exposure parameters for a given entity, the respective entity | |
must be selected by the user. Graphical elements (Designer and SmartFIB Live | |
Mode only) are selected using the mouse. Positions (SmartFIB only) are selected | |
using the mouse or by selecting the respective entry in the Process List tab. Layers | |
(Designer and SmartFIB Live Mode) are implicitly selected via the empty selection by | |
clicking an empty region. Exposure parameters of graphical elements and layers are | |
specified in the Exposure Parameters tab located in the Attributes tab (Designer | |
and SmartFIB Live Mode) or the Exposure Parameters tab in the Settings tab | |
(SmartFIB Sample Mode). Exposure parameter sets are always complete, i.e. it is not | |
possible for an entity to partially use a set of exposure parameters. It is, however, | |
possible for an entity to inherit exposure parameters which means that exposure | |
parameters required for the actual exposure of an entity can be defined either | |
directly via explicit specification or indirectly via inheritance. | |
Exposure parameters are resolved by applying the following rules: | |
1 If a position specifies exposure parameters then every graphical element in the | |
position uses these exposure parameters. | |
2 If a graphical element specifies exposure parameters and the associated | |
position does not then the graphical elements exposure parameters are used. | |
3 If neither the position nor the graphical element specifies exposure parameters | |
then the exposure parameters of the graphical elements layer are used. | |

3.4.2 Conversion Factors of Units | |
The following equations can be used to calculate parameters for exposure | |
processes. | |
Equation Description | |
The area dose is defined as electric charge | |
per area in micro-Coulomb per square- | |
centimeter. Beside its general meaning as | |
a dose value for exposure (see: Exposure | |
tab) the area dose is also relevant for the | |
image capture during an Alignment | |
process (see: Capture area tab) ). Image | |
capture causes some undesirable | |
background dose within the capture area. | |
Hence it is necessary to incorporate this | |
area dose for the following exposure | |
process. On the one hand the overall | |
background dose must not exceed a | |
certain critical value. For resist processes | |
the capture area ought to be not disolved | |
by the developer and for beam induced | |
processes the deposition or removal of | |
material should be minimized. The area | |
dose rises with the resolution for a fixed | |
Pixel time. | |
Line elements are exposed as a chain of | |
single pixels along the direction of a line. | |
Therefore these "one dimensional" | |
elements are also called "single pixel line". | |
The line dose specifies the electric charge | |
per length unit in pico-Coulomb per | |
centimeter. | |
For point elements, the dose is just the | |
electric charge per point in femto- | |
Coulomb | |

Control Element Description | |
Selection: readout The recipes are assigned to either a position | |
(in Sample Mode), a layer or an element (Live | |
Mode and Designer). The Selection informs | |
you with which of this entities your recipe | |
assignment is dealing at the moment. This is | |
especially important as it is possible to use | |
multi sections (of the same entity) also. | |
Ignore checkbox When your current selection holds elements, | |
than you are able to check the Ignore flag. | |
This will prevent the elements from exposure | |
even when the exposure is carried out for the | |
corresponding process (see also context menu | |
for right click on element selections). The | |
status of ignored elements is indicated by a | |
stippled filling pattern for the elements. | |
Material: drop-down list Allows you to assign recipes to the Selection | |
directly or if so to decide about other | |
modalities of the exposure parameter | |
assignment. | |

Control Element Description | |
Create Recipe button | |
The Create Recipe button allows to edit | |
a recipe. | |
Save button | |
The Save button allows to save a recipe. | |
Purpose: drop-down list In SmartFIB it is obligatory to state a purpose | |
for each recipe (FIB Milling, FIB deposition, | |
SEM Lithography or SEM Deposition). For | |
assigned recipes this purpose is displayed just | |
for informing the user. Whereas when you | |
edit a recipe (in Exclusive Mode) changing the | |
purpose by means of the drop-down list will | |
adapt the appearance of the Recipe dialog for | |
editing recipes for the chosen purpose. This is | |
achieved by setting certain default values and | |
offering only a subset of relevant parameters | |
for editing in the particular sections (details | |
see below). | |
Gauging: drop-down list Indicates if the current set of exposure | |
parameters or the used recipe is gauged or | |
not gauged i.e. if the set of parameters is | |
calibrated for a certain height or depth. | |
For more information refer to the Info section | |
at the end of this topic. | |
Probe: drop-down list Allows you to quickly change the used probe | |
for the recipe. Please be aware that although | |
the scanning parameters such as spacing and | |
dwell-time are recalculated for the new probe | |
there might be significant changes in the | |
result of the exposure. For SEM-purposes this | |
drop-down menu is not available. | |
Dose factor: input field and | |
arrow buttons | |
Only for element selections. This user input | |
field allows you to scale the overall dose for | |
the recipe by means of a factor. | |

recipes you can set a Depth or a Height (or in | |
case of SEM Lithography a scaling Value) to | |
scale the overall dose for the entity. SmartFIB | |
calculates automatically the necessary changes | |
in the exposure parameters in order to reach | |
the stated result. You can control the | |
calculation by choosing the computed | |
parameter (see also: Dwell time and Cycles in | |
the Details section). For non-gauged sets of | |
exposure parameters the Depth/Height user | |
input field is deactivated. | |

1 Inconsistent | |
A selection can contain more than one entity of the same type | |
(elements, layers or positions). If the assigned recipe is not the same | |
for all entities of the Selection this is indicated by the entry: | |
inconsistent in the Materials drop-down list. | |
None | |
As the layer is the lowest entity in the assignment hierarchy layers | |
cannot take exposure parameters from another entity. Therefore | |
when you do not directly assign a recipe to a layer this is indicated by | |
the entry: None in the Materials drop-down list. | |
From Layer | |
Whenever you have not directly assigned a recipe to an element | |
selection the Material drop-down list is indicating this by the entry: | |
from Layer. This means that the element exposure parameters are | |
taken from the Layer settings. Assigning a recipe to the layer and | |
leaving the element Material settings: from Layer is a convenient way | |
to assign the same recipe to a larger number of elements. | |
From Layout | |
Sample Mode | |
Whenever you have not directly assigned a recipe to a position | |
selection the Material drop-down list is indicating this by the entry: | |
from Layout. This means that the exposure parameters are taken from | |
the Layout settings, i.e. from the layers or the elements according to | |
the assignment hierarchy. | |
Exclusive | |
Assigned recipes can be adapted by changing a few special | |
parameters (see below). For more flexibility or in order to create new | |
recipes Exposure parameters can also be assigned to entities | |
independent from saved recipes. | |
This allows you to edit all the individual parameters directly. To | |
achieve this you can either choose the entry: Exclusive in the Material | |
drop-down list or click at the (Create Recipe) Pen button next to the | |
Material drop-down list. | |
If there are any previously assigned parameters they will be used as | |
default when changing to Exclusive Mode. Doing so the Pen button | |
changes to the Save Changes button. By pressing this button the | |
user is offered a possibility to save the edited set of exposure | |
parameters as a new recipe. Apart from user saving the edited recipe | |
as a new recipe / can even overwrite the existing recipe as well. | |

Info: The Basic Idea of | |
Gauging | |
The general assumption for the idea of gauging recipes is that a process which is | |
controlled by a set of exposure parameters delivers matchable results with respect | |
to milling depth or deposition height for repeated usage when basic conditions for | |
the process (such as used substrate or beam energy) are kept unchanged. | |
Furthermore it is assumed that the achieved milling depth or deposition height can | |
be scaled over a wide range by just scaling the overall-dose. This is surely not true | |
for all set of exposure parameters and of course there are limits for the simple | |
assumed scaling behavior. | |
Nevertheless there are many situations where the implementation of this simple | |
paradigm provides practical results for the used processes. Eventually this amounts | |
to the concept of scaling the milling depth or deposition height directly by | |
inserting the desired depth or height in units of length. This can be achieved by | |
measuring the resulting depth or height once for the process and insert the value | |
as reference value for the recipe. When this is done the recipe can be reused for | |
different depth or height by just entering the desired value in the Depth/Height user | |
input field of the common section of the recipe tab. | |
The user does not need to care about dose scaling or such things when he reuses | |
the recipe. In fact he normally does not even look into the Details section of the | |
Recipe tab at all. He rather chooses the recipe, states the desired depth or height | |
and starts the exposure. It is recommended therefore to create and use gauged | |
recipes for everyday work whenever it is possible as this reduces the complexity of | |
parameter assignment enormously. This is also the reason why the parameter | |
assignment for ASP elements works with gauged recipes only. | |
4.5.3.1.1.1 Exposure Preview | |
Exposure parameters may be defined in complex procedures for graphical | |
elements, for layers and for positions. Taking full advantage of these possibilities | |
makes it increasingly difficult to judge the validity of an elements exposure | |
parameters with respect to a given microscope. | |
4 User Interface | 4.5 Control Panel | |
Software Manual SmartFIB | en1.2 | 346000-8083-000 73 | |
The Preview dialog can be used to alleviate the situation. They show the exposure | |
parameters resulting from the currently edited exclusive exposure parameters and | |
also display values that may be accompanied or replaced by informational texts in | |
case of errors. Previews can be applied to multi-selections as well. If a parameters | |
value is consistent across the selected entities, a single value will be shown, if it is | |
ambiguous, a range of values with lower and upper bounds is computed and | |
displayed. | |
The Preview dialog is not modal and is updated when the exposure parameters are | |
manipulated. It is therefore possible for the user to gradually approach dwell time | |
limits, etc. As unchanged probes are not resolved by the system, previews are | |
unsupported if at least one selected set of selected exposure parameters uses the | |
unchanged probe. In this case, the Preview button is insensitive. | |

4.5.3.1.3 Details | |
The expandable section Details is a rather comprehensive and varied dialog which | |
allows the user to control the exposure process in detail. In order to avoid | |
unneccesary complexity the apperance of the dialog is adapted to the specific | |
situation. Depending on the Selection and the purpose of the recipe for example | |
the dialog consists of different fields for stating values for Points, Lines and Areas. | |
When you have selected entities with inconsistent values the corresponding field | |
are left blank or not valid. | |

Section Control Element Description | |
Points This field is only available for SEM Lithography and SEM deposition when the Selection is either | |
Layers, Positions or in case of element Selection when it contains Point elements. | |
Dose: input field with arrow | |
buttons | |
Indicates the overall dose for Point elements (unit: nC) which was | |
set for the recipe either directly for non-gauged exposure | |
parameters or for gauged recipes via the Depth/Height entry in | |
the common section. | |
Dwell time: input field with | |
arrow buttons | |
Indicates the duration of the dwell for each individual raster point | |
for a separate cycle. Depending on the selection and the chosen | |
computed parameter (for SEM deposition) this sub-field is | |
showing either the computed Dwell time, the stated Dwell time | |
for the recipe or not valid in case of a Selection that results in | |
inconsistent values for the Dwell time. | |
Cycles: input field with arrow | |
buttons | |
This sub-field is only displayed for SEM deposition. | |
For SEM Lithography the value is set implicitly to 1 and the | |
computed parameter is therefore always the Dwell time. For | |
points the number of Cycles being not 1 only makes sense in | |
case of very high dose values so that the maximum Dwell time | |
for one Cycle is exceeded or when you want to expose the point | |
in intervals with inserted cycle delay, see Precision [- 86]. | |

Lines This field is available only for SEM Lithography and SEM deposition when the Selection is either | |
Layers, Positions or in case of element Selection when it contains Line elements. | |
Dose: input field with arrow | |
buttons | |
Indicates the overall dose for Line elements (unit: µC/cm) which | |
was set for the recipe either directly for non-gauged exposure | |
parameters or for gauged recipes via the Depth/Height entry in | |
the common section. | |
Pixel spacing: input field with | |
arrow buttons | |
Allows to define the step width for the individually scanned pixels | |
along the line. The unit for the Pixel spacing of Lines is always | |
stated directly in nm (as the Lines section is only shown for | |
electron beam processes where no beam diameter is available for | |
the probe). | |
Note that for a given Dose changes in the Pixel Spacing | |
automatically will adapt the Dwell time or the number of Cycles | |
depending on the actual computed parameter. | |
Dwell time: input field with | |
arrow buttons | |
When you have chosen SEM deposition for the Purpose of the | |
recipe than you can set the duration of dwell for the individually | |
scanned pixels along the line in units of µs by means of this input | |
field. When you change the value the number of Cycles will be | |
automatically set as the computed parameter. If on the other | |
hand the Purpose of the recipe is chosen to be SEM lithography | |
the Dwell time field informs you about the calculated duration of | |
dwell for the individually scanned pixels as a result of the other | |
parameters of the recipe. In this case the number of cycles is set | |
implicitly to one and the computed parameter is therefore always | |
the Dwell time. | |
Cycles: input field with arrow | |
buttons | |
This sub-field is only displayed for SEM deposition and is used to | |
set the number of repeats for the scan, see Scanning [- 81]. | |
For SEM Lithography the value is set implicitly to 1 and the | |
computed parameter is therefore always the Dwell time. . | |

Indicates the overall dose forArea elements (unit: mC/cm2 | |
) which | |
was set for the recipe either directly for non-gauged exposure | |
parameters or for gauged recipes via the Depth/Height entry in | |
the common section. | |
Pixel spacing: input field with | |
arrow buttons | |
Allows to define the step width for the individually scanned pixels | |
along the fast direction of the scan (pixel feed). The unit for the | |
Pixel spacing of Areas is stated directly in nm for electron beam | |
processes as there is no beam diameter available for the probe in | |
this cases. For FIB processes on the other hand the default unit | |
for the Pixel spacing is percentage of the probe diameter but | |
nevertheless the user has the possibility to select the unit to be | |
nm for the Pixel spacing by using the unit drop down menu. | |
Note that independent of the chosen unit the resulting filling | |
pattern is schematically displayed in the expandable section: | |
Scanning for FIB processes. Please note also that for a given Dose | |
changes in the Pixel spacing automatically will adapt the Dwell | |
time or the number of Cycles depending on the actual computed | |
parameter. | |
Track spacing: input field with | |
arrow buttons | |
Allows to define step width for the individually scanned tracks | |
along the slow direction of the scan (line feed). The Track spacing | |
is synchronized (locked) to the Pixel spacing by default. In order | |
to choose the value and/or the unit for the Track spacing | |
independently you have to unlock the synchronization of the two | |
parameters by means of the lock button. The unit for the Track | |
spacing of Areas is stated directly in nm for electron beam | |
processes as there is no beam diameter available for the probe in | |
this cases. For FIB processes on the other hand the default unit | |
for the Track spacing is percentage of the probe diameter but | |
nevertheless the user has the possibility to select the unit to be | |
nm for the Track spacing by using the unit drop down menu. | |
Please note that independent of the chosen units the resulting | |

automatically set as the computed parameter. If on the other | |
hand the Purpose of the recipe is chosen to be SEM lithography | |
the Dwell time field informs you about the calculated duration of | |
dwell for the individually scanned pixels as a result of the other | |
parameters of the recipe. In this case the number of cycles is set | |
implicitly to one and the computed parameter is therefore always | |
the Dwell time. | |
Cycles: input field with arrow | |
buttons | |
For SEM Lithography this field is not displayed at all but the value | |
is set implicitly to 1 and the computed parameter is therefore | |
always the Dwell time. For the other purposes the Cycles input | |
fields is used to set the number of repeats for the scan. | |
Depending on the scan mode (see: Expandable section Scanning) | |
the Cycle number has a different. In any case apart from | |
scanning images it describes how often each individual scanning | |
point is touched by the beam during the exposure. | |
Ref-Height: input field with | |
arrow buttons | |
Whenever you are using a gauged recipe this field informs you | |
about the reference value which was inserted for gauging (see | |
Gauge/Regauge button). Please note for non-gauged recipes the | |
displayed value is 0.000 nm. | |
Gauge / Regauge button Depending on the status of the recipe (gauged or non-gauged) | |
the label of the button changes between Gauge and Regauge | |
(see also Gauging in the Common [- 67] section of the Recipe | |
tab). In both cases following Gauging dialog opens. | |
Gauging Dialog Enables the user to gauge, regauge or remove an existing gauging of a recipe or | |

Info: Deriving Values From | |
Area Settings for FIB Purposes | |
Recipes for applying the FIB (purpose: FIB Milling or FIB deposition) do not involve | |
separate fields for Points, Lines and Areas but rather offer the Area field only for all | |
situations. This is because in such cases a mechanism to derive the Line and Point | |
values is implicitely utilized. The basic idea is to take into account the nonzero | |
diameter of the FIB probe which results in an exposed Area (2-dimensional) also | |
for Lines (in principle 1-dim) and Points (in principle 0-dim). The following | |
equations are applied: | |
DosePoint = (DoseArea * beam diameter2 | |
* pi)/4 | |
DoseLine = DoseArea * beam diameter | |
Pixel SpacingLine = Pixel SpacingArea | |
The values for Cycles and Dwell times for Lines and Points are synchronized to the | |
corresponding Area parameters. | |
Info: Computed Parameter The values for the individual fields of Point, Line or Area are also not completely | |
independent. In order allow for full flexibility and to avoid overdetermination there | |
is the concept of the computed parameter. | |
This concept allows for keeping the set of parameters consistent by making either | |
the number of Cycles or the Dwell time dependent on the other parameters. This | |
dependent parameter is indicated by the label (computed) behind the user input | |
field. Whenever you change one of the other parameters the computed parameter | |
is calculated automatically to keep the complete set of exposure parameters | |
consistent. If you change the value of the momentarily computed parameter the | |
role of the computed parameter is shifted to the other possibility (fom Cycles to | |
Dwell time or vice versa) and the just changed value will be kept constant from | |
now on when changing other parameters than Cycles or Dwell time. | |
For the purpose beeing SEM Lithography the computed parameter is always the | |
Dwell time and the number of cycles is set to 1 implicitly. | |

Info: Changing the Dose | |
Value for Gauged Recipes | |
When applying gauged recipes the scaling factor for the dose is based on the Area | |
Dose value which was used during gauging the recipe. Therefore whenever you | |
change the Area dose value for an already gauged recipe the following dialog | |
pops up: | |
Clicking the Yes button removes the gauging from the current set of exposure | |
parameters and quits the dialog. | |
Clicking the No button will restore the Area Dose value which was used during | |
gauging the recipe and quits the dialog. | |
Info: Gauging for Different | |
Element Types | |
The dose for gauged recipes is scaled uniformly for Point, Line and Area elements. | |
When you are working with area elements exclusively the gauging process is | |
straightforward. It just relates the Area dose to the Ref-Depth/Height and scales | |
the dose according to the stated Depth/Height and Probe. For Recipes applying the | |
FIB (purpose: FIB Milling or FIB deposition) the dose for Points and Lines is then | |
also scaled as the values are derived from the Area parameters. However this | |
deriving will not work well enough under all circumstances. Therefore if you notice | |
a big discrepancy between the Depth/Height for Points, Lines and Areas when | |
using the same gauged recipe you should gauge the recipe for each element type | |
seperately and save them (with a hint to the element type in the recipe name). | |
Thus you can apply the recipes independently for the different element types. The | |
situation is slightly mor complex for electron beam purposes as one has to state | |
the dose values for the three element types individually as there is no deriving of | |
dose values for Points and Lines. Here too the easiest way to deal with this | |
situation is to create separate gauged recipes for each element type. If you like | |
you can combine the recipes to one later on. | |

4.5.3.1.4 Scanning | |
The expandable section Scanning allows you to control the sequence of the | |
individually scanned pixels of the elements | |
Control Element Description | |
Mode Fast: drop-down | |
menu | |
Offers three entries which describe the relative orientation of two subsequent scanning | |
tracks (lines) of the filling pattern (thin black arrows in the illustration on the right hand | |
side of the drop down menu). | |
Unidirectional: All subsequent tracks are scanned in the same direction. | |
Bidirectional: The tracks are alternately scanned in opposite direction. | |
By purpose: The relative orientation of two subsequent tracks is determined by | |
the purpose of the recipe, see also Common Section [- 67], which is bidirectional | |
for the four momentarily used purposes (FIB Milling, FIB Deposition, SEM | |
Lithography or SEM Deposition). | |

82 Software Manual SmartFIB | en1.2 | 346000-8083-000 | |
Control Element Description | |
Cycle Mode: drop- | |
down menu | |
Allows to specify how the number of Cycles is used to affect the sequence of the | |
scanning tracks on a global view (light grey arrows in the illustration on the right hand | |
side of the drop-down menu). | |
Loop: The element is filled by scanning each track only once in the first pass. The | |
scan is continued in identical repetitions of the first pass. The total number of | |
repeats is determined by the number of Cycles stated in the Details section. This | |
scan mode is normally used for milling processes when a uniform depth of the | |
milled area has to be achieved. | |
Back-and-forth: The element is filled by scanning each track only once in the first | |
pass. The second pass is scanned by retracing the first pass with reversed | |
orientation regarding track sequence and direction of the individual tracks. The | |
scan is continued by identical repetitions of the first pass for odd pass numbers | |
and identical repetitions of the second pass for even pass numbers alternatingly. | |
The total number of passes is determined by the number of Cycles stated in the | |
Details section. This scan mode is normally used for deposition processes. | |
Cross-section:Before moving on to the next track each individual track is scanned | |
again and again until the the total number of repetions is reached. For the Mode | |
Fast beeing bidirectional every second repetion of the track will be scanned with | |
reversed orientation. The total number of repetions for each track is determined | |
by the number of Cycles stated in the Details section. Thus the subsequent tracks | |
are finished completely one after the other before the next track is touched at all. | |
This scan mode is used normally to reach high milling rates whenever a | |
pronounced redeposition of material can be tolerated. | |
Serial-section:Same scan style as when choosing cross-section but additionally | |
allows to choose a number of Tracks after which a SEM-image can be grabbed | |
automatically during the milling process, see also Obtaining Serial Section Images [ | |
- 168]. | |
By purpose: The Cycle Mode is determined by the purpose of the recip, see also | |
Common Section [- 67]. | |

For FIB recipes on the right side of the expandable section Scanning the filling | |
pattern is sketched. It takes into account the relative dimensions of probe diameter | |
(diameter of the circles), Pixel spacing (horizontal distance of the circles) and Track | |
spacing (vetical distance of the circles). The following example illustrates the | |
situation for 100% Pixel spacing and 50% | |
Track spacing: | |
Info: Element Specific | |
Geometry of the Scanning | |

5.1 General Assumptions | |
There are some prerequisites that have to be fulfilled when working with SmartFIB. | |
TIP | |
To make it easier to fulfill the prerequisites in SmartSEM, refer to the Software | |
Manual SmartSEM XB for details. | |
FIB and SEM have to be ready for use | |
FIB gun is on (no error messages) | |
All FIB probe currents to be used have to be defined and aligned (refer to the | |
Software Manual SmartSEM XB, "Defining user-specific FIB probe currents") | |
GIS needs to be ready for use (Refer to the GIS Instruction Manual for | |
instructions on outgassing, initializing etc.) | |
It is recommended to move the specimen to the coincidence point. When | |
working with the GIS, this is mandatory. | |
It is recommended to adjust the eucentricity, especially for automated | |
processes. | |

In the following two main workflows are illustrated: | |
Performing a Basic Exposure/Milling process [- 148] describes a basic | |
procedure that uses Live Mode only. The other procedures are based on this | |
section. | |
Performing a Multi-Site Exposure/Milling Workflow [- 153] describes how to | |
work with objects that have transferred from Live Mode to Sample Mode. | |

5.2.1 Performing a Basic Exposure/Milling process | |
The following section describes a basic exposure/milling process using Live Mode | |
only. | |
The procedure contains the following steps: | |
Acquiring an Image [- 148] | |
Creating Shapes/Elements to be Exposed/Milled [- 149] | |
Setting the Exposure/Milling Parameters [- 150] | |
Starting the Exposure/Milling Process [- 152] | |
5.2.1.1 Acquiring an Image | |
First step of a basic exposure/milling workflow is to acquire a FIB image. This image | |
serves as an orientation for placing geometric elements to be exposed/milled at the | |
right position. | |
You can acquire a FIB image only in Live Mode. | |
Procedure 1 In SmartSEM, select a proper detector (SESI or InLens). | |
2 Roughly approach the desired position. | |
3 Go to the SmartFIB user interface. | |
4 On the Standard Toolbar, click the Live Mode icon. | |
5 Select the Image Capture tab. | |
6 To start the scan, click Cycle. | |
An image appears in the Working Area. | |
7 To optimize the image, adjust the scanning parameters and use a reduced | |
raster if necessary. | |

8 If the image quality is sufficient to position geometric elements with adequate | |
accuracy, click Capture. | |
5.2.1.2 Creating Shapes/Elements to be Exposed/Milled | |
Once you have acquired a FIB/SEM image in SmartFIB, you can start to create | |
elements / shapes by using the drawing tools on the Tools Toolbar. | |
Prerequisite You have acquired a FIB/SEM image | |
Procedure 1 On the Tools Toolbar, select a drawing tool. | |
The cursor changes to match the selected shape. | |
2 Move to the desired position. | |
Click and hold down the left mouse button while moving the mouse. | |
A preview of the selected shape appears. | |
3 Release the mouse button. | |
This will create the desired shape (some elements, such as trapezoids, require | |
additional steps). The Attributes tab opens in the Control Panel. This tab | |
shows element-specific parameters. | |
You can change these settings to adjust the properties of the geometric | |
element. | |
4 Once you have finished drawing, switch back to the Select tool by clicking the | |
icon. | |
This allows you to move, erase change, rotate elements | |
5 Working with the Software | 5.2 General Operation | |
150 Software Manual SmartFIB | en1.2 | 346000-8083-000 | |
TIP | |
You can resize and rotate already drawn shapes/elements. | |
To toggle between resizing and rotating, click once into the element/shape. | |
The marks around the element/shape change accordingly from for | |
resizing to for rotating and vice versa. | |
Move the cursor above one of the resize/rotate marks. The cursor will | |
change accordingly. Then, click and drag with the mouse. | |
5.2.1.3 Setting the Exposure/Milling Parameters | |
Now that you have drawn geometric elements on the background image, you have | |
to assign scanning and exposure parameters to the created elements. | |
In Live Mode, you can choose between setting parameters for the whole layer and | |
exclusive parameters for single geometric elements and for multi-selections. If an | |
element defines parameters other than none, then the layer parameters are | |
overwritten. To be able to understand how these settings interact, refer to section | |
Hierarchy of Exposure Parameter Assignment [- 31]. | |
Prerequisite You have created a background image | |
You have drawn some geometric elements | |
Procedure 1 Select an element, a group of elements or a layer. | |
2 On the Control Panel, select the Attributes tab > Recipe. | |
3 Choose a recipe from the Material drop-down list. | |
For more information refer to Recipe [- 66]. | |
4 You can select a different probe from the Probe drop-down list. | |
5 You can set depth by the input field. | |
6 Click Preview. | |
The Exposure Preview window opens. The preview shows if there are any | |
problems with the chosen settings. This makes it easier to find suitable | |
exposure settings and to learn how the various parameters interact. Once | |
there are no entries with red text left, you can be sure that the settings will | |
result in a working exposure. | |

5.2.1.5 Starting the Exposure/Milling Process | |
You have almost reached your goal: you have created a background, drawn | |
geometric elements and assigned exposure parameters. | |
Everything that remains to be done is to start the exposure. | |
Prerequisite You have created a background image | |
You have drawn some geometric elements | |
You have set the exposure parameters | |
Procedure | |
1 On the Standard Toolbar, click the Expose icon. | |
On the Control Panel, the Exposure dialog opens. | |
2 Change the desired settings. For a detailed description of each parameter, refer | |
to the section Exposure [- 140]. | |
3 Select an entry from the On End Mill: drop-down list. | |
This enables you to be able to see the result of the exposure process as soon | |
as it is finished, or to trigger an operation of the microscope. | |
4 To start the exposure, click Start. | |
The process starts and various readouts show the current status of the | |
exposure process. | |
To make sure that you can observe the exposure/milling process with the SEM, | |
the default selection on theOn Start Mill drop-down list is SEM. | |
As soon as the exposure process has finished, SmartFIB will switch to the | |
defined On End Mill: setting. | |
The default setting is SEM. The SEM image is scanning in SmartSEM when the | |
exposure/milling process is finished in SmartFIB. | |
This concludes the most basic workflow for working with SmartFIB. You can | |
now proceed to more complex tasks. | |
TIP | |
If you experience any issues with blurry edges of exposed elements, you can try | |
to select a different scanning setting in the Scanning section of the Recipe tab. | |
5 Working with the Software | 5.2 General Operation | |
Software Manual SmartFIB | en1.2 | 346000-8083-000 153 | |
Depending on the selected geometric elements and also their orientation, you have | |
to consider an appropriate scanning strategy. | |
The parameters Delay and Cycle Delay can also be helpful. | |
TIP | |
The nudge control function allows you to shift and rotate elements during the | |
exposure/milling process. You don't have to stop the whole process to do minor | |
corrections. This can be especially useful while preparing a TEM lamella. | |
To use nudge control, activate the Nudge checkbox in the Exposure dialog | |
before you start the exposure. | |
5.2.2 Performing a Multi-Site Exposure/Milling Workflow | |
Requires the licence AUTOPREP. | |
Compared to Performing a Basic Exposure/Milling process [- 148],which only uses | |
Live Mode, the following example shows a very simple multi-site exposure/milling | |
workflow using both Live Mode and Sample Mode. | |
You can expand this principle to more challenging tasks. | |
Procedure 1 In Live Mode, draw some geometric elements as described in Creating | |
Shapes/Elements to be Exposed/Milled [- 149]. | |
2 Apply a drift correction as described in Using a Drift Correction [- 151]. | |

5.3.8 Transferring Layouts to Sample Mode | |
Requires the licence AUTOPREP. | |
One of the key operations in SmartFIB is to transfer layouts from Live Mode to | |
Sample Mode. This allows you to arrange scanning areas and to perform other | |
tasks that are only available in Sample Mode. | |
Prerequisite You have drawn some geometric elements | |
Live Mode is active | |
Procedure | |
1 On the Standard Toolbar, click the Tranfer to Sample Mode icon. | |
The transferred positions and dwell times are indicated in the Standard Toolbar | |
next to the Tranfer to Sample Mode icon. | |
2 Verify that the geometric elements have successfully been transferred to | |
Sample Mode: You can find the transferred structure layer in the Process List | |
tab > Transferred. | |
3 To start the exposure of the transferred layouts, switch to sample mode . | |
Working with the Software | | |
5.4 Working in Sample Mode | |
Sample Mode | |
Allows you to process multiple scanning areas e.g. of different size and to | |
position them on the specimen | |
The focus is on the layout-oriented approach | |
Mainly used for | |
Recurring/automated workflows | |
Combination of different structuring processes: If the specimen has been | |
modified before, there is also information given (e.g. Lithography) | |
CAD layout navigation | |
Documentation of processes and specimens (which steps were carried out? | |
Repeatability) | |
Simulation of complex processes also possible in offline mode | |

160 Software Manual SmartFIB | en1.2 | 346000-8083-000 | |
5.4.1 Performing a Sample Adjustment | |
After loading a specimen into the specimen chamber, the absolute position and the | |
angle between sample coordinate system and stage system are defined. | |
The adjustment procedure makes it possible for the program to calculate the | |
coordinate transformation from the stage system to the sample system. | |
The Sample Adjustment dialog provides a comfortable way to acquire the real | |
adjustment. After this procedure, you can work with sample coordinates and you | |
will not have to mind any translation problems, for example when moving the | |
stage. | |
If you do not apply any sample adjustment, the first writing position will be | |
connected with the current stage position, the angle will be implicitly set to 0.00. | |
Procedure 1 Focus a point (A) at the bottom edge of the specimen. | |
2 On the Menu Bar, select Sample > Adjustment... . | |
3 Click (south) and insert the correct Y value (e.g. 0.00) in the Y: input field. | |
4 Click Add. | |
The point is added to the Positions list. All entries in this list are used for the | |
calculation. | |
5 Proceed the same way with another point (B) at the bottom edge of the | |
specimen. | |
Now the system is able to calculate the stage angle correction. The result is | |
displayed in the list at the bottom of the Sample Adjustment dialog. | |
5 Working with the Software | 5.4 Working in Sample Mode | |
Software Manual SmartFIB | en1.2 | 346000-8083-000 161 | |
6 Choose a point (C) on a neighbouring edge and click (west). Insert the | |
correct X value (e.g. 0.00) in the X: input field. | |
7 Click Add. | |
Now, the system can calculate absolute positions. The Sample-stage system: | |
readout changes from not connected to connected. | |
For multi-site processes with different stage rotation or stage tilt the | |
adjustment is always in an indifferent state indicated by indifferent. | |
This was just a simple example to show how the Sample Adjustment dialog is | |
working. There are a lot of variations and the Sample Adjustment dialog is aimed | |
at attaining as much information as possible of your chosen set of adjustment | |
points and avoiding overdetermination. | |
5.4.2 Using the Process List | |
SmartFIB offers a process list. This list helps you to keep track of any steps you | |
made during your work with SmartFIB. This allows you to backtrack your steps | |
easily and to increase repeatability. | |
TIP | |
To be able to use the full functionality of the process list, the licence AUTOPREP | |
is required. | |
It allows you to transfer shapes/elements to Sample Mode and to return to | |
previously processed steps and positions. | |
TIP | |
You can start the exposure of the created process list without switching to | |
sample mode. | |
Therefore just open the Process List tab, select Transferred and click | |
Expose. | |
TIP | |
You can add different layouts at completely different stage positions to the | |
Process List. While this list is is executed SmartFIB will move the stage to the | |
according position. | |

5.5.4 Obtaining Serial Section Images | |
Serial section images are a basic functionality for generating 3D datasets. | |
Afterwards, the data can be compiled to a 3D image using specific software (e.g. | |
ORS ). | |
SSI is a scanning mode also, which will not deliver nice depositions. | |
TIP | |
The process is based on an alternating sequence. The milling is started in SmartFIB | |
and repeatedly paused for image acquisition in SmartSEM. | |
Procedure 1 Prepare an edge from which you want to start using the cross-section Cycle | |
mode in Live Mode. | |
2 Prepare a U-shaped area around the element. | |
This ensures that there is no material around the element. This minimizes | |
shadowing effects and redeposition. | |

5.6.2 Gas-Assisted Etching | |
Gas assisted etching (GAE) allows you to selectively increase etching rates | |
comparing to etching with the ion beam or the electron beam alone. | |
Etching Reagent Selectively Etches | |
Xenondifluoride, XeF2 Si, SiO2 | |
Water (reactive products) Carbon, organic materials | |
Milling Objects Etching is done by processing a milling object, usually with the specimen stage at | |
54. | |
There are different etching types: | |
Physical etching: only the ion beam is used to remove material | |
Chemical etching: the ion beam and precursor gases are used to remove | |
material | |

Fig. 38: Comparison between silicon etching (without gas) and gas assisted | |
etching (with fluorine) | |
Types of Etching | |
Physical etching | |
Ion milling Physical etching means that only the ion beam is used to | |
remove material within a selected area (1). The removed | |
material is re-deposited (2) at the side walls faster than it can | |
be pumped away. Therefore, the side walls are uneven and | |
the ability to mill deep holes is limited. | |
Chemical etching | |
Gas assisted | |
etching (GAE) | |
GAE means that the ion beam hits a selected area (3) on the | |
specimen surface and interacts with a precursor. The precursor | |
is split up into a volatile, inactive substance and a volatile | |
active substance. The inactive substance is pumped away. The | |
volatile active substance reacts with the substrate and | |
becomes a volatile compound which removes the substrate. | |
Using GAE improves the aspect ratio of the milled holes and | |
enhances the removal rate. Thus, the sidewall angles come | |
closer to 90 (4). | |
Selective etching GAE is also material-selective, because etching reagents etch | |
different materials (5,6) at different rates. | |

5.6.3 Electron Beam Deposition | |
Depositing and etching with the electron beam is a suitable method for materials | |
that cannot be processed with the focused ion beam. | |
Another advantage is that there is no impairment of surfaces (e.g. no generation of | |
amorphous layers). | |
