ATLAS is a universal image processor for capturing, displaying, processing, analysing, searching, and archiving images obtained from different image sources such as electron microscopes or dual beam systems.
The program contains an image manager system allowing users to store their images in albums, find specific images or groups of images based on a variety of criteria such as acquisition date, microscope’s name, project’s name, operator’s name, microscope’s parameters for image acquisition, detector used, resolution, microscope’s operation mode, for acquiring the image, and more.
ATLAS runs on a Windows™ platform and can export files to MS Word simplifying in this way the creation of reports based on customisable templates. The images can be saved in a variety of standards formats (e.g. jpeg, tiff, bmp, etc.).  Atlas is multi-user software, thus each user’s environment and settings are saved after logging-off and automatically restored back on a new session. Built as a modular system, the functionalities of Atlas can be expanded by means of plug-in modules and according to particular analytical needs.
Standard modules tools in the ATLAS software include:
  • Histogram:  Allows displaying the image histogram equalisation of the active window. Contrast/brightness can be simply changed by three arrows (black or white level and gamma correction).
  • Live Video: Allows the user to process the image captured by means of a video camera or other image recording device connected to the PC. Help monitoring
  • Measurement: Intended for measuring lengths, areas or angles of objects in an image. The module can also insert descriptions, scale bars, markers, auxiliary arrows and set a grid over the image. The measurement results can be saved into a file which can be opened by a text or spreadsheet processor.
  • Particles: Module intended for morphological analysis of objects (particles, grains, fibres, etc.).
  • Hardness: Intended for measuring material hardness by means of the Brinell or Vickers method.
  • Image processing: Provides an extensive set of image editing functions - resizing and cropping, noise reduction filters, various edge and structure detectors, manual and automatic brightness and contrast adjustment functions and several colour enhancement filters.
  • Multi Image Calibrator: Allows the user to automatically calibrate the set of images, i.e. setting the pixel size. This information is used by other modules (e.g. Measurement) for the measurement of lengths or areas in physical units (millimetres, inches, nanometres, etc.).
  • Object Area: Intended for calculating areas selected in an image. The region is defined by the colour (brightness) of the pixels lying within the region. The region is set off with the selected colour and it is possible to calculate its area. The region must be distinguishable in brightness or colour shade. Various images can be processed at the same time, and the obtained results can be saved into a text file.
  • Tolerance: Intended for quick control of objects dimensions and dimensions tolerance.
  • Report Generator: Allows users to create printable documents based on predefined templates such as reports.

Integrated circuit device modification using Camelot
As the complexity of Integrated Circuit (IC) design modifications increase, the time to perform these modifications also increases. As a result, the turn-around-time for bug fixes becomes critical to a product’s success. The Focused Ion Beam (FIB) is powerful tool for circuit edit because it can remove and deposit materials with high precision. These capabilities can be used to cut and connect circuitry within a device, as well as to create probe points for electrical test. To execute circuit edits, the FIB tool is coupled to a CAD navigation system that makes it possible to locate the area of interest.

AutoSlicer enables automation of FIB-SEM operations such as serial cross-sectioning and lamellae preparation or other objects defined at multiple locations. Overnight and unattended operations can be set.
The full automation of these processes helps to increase the productivity of the system and saves the operator’s effort. By defining multiple objects on multiple sites, the module allows for setting the process for overnight and unattended operation.

3D Tomography

3D Tomography is dedicated software for performing FIB-SEM tomography and the subsequent 3D reconstructions from the collected data.

Different visualisation methods are available and data post-processing is also possible.

The module consists of the following parts:

  • Milling and image acquisition wizard
  • Data post-processing
  • 3D reconstruction and visualization


Data Acquisition

The Acquisition Wizard guides the operator to set optimal milling and imaging parameters. The region of interest is selected in the FIB window and some parameters related to milling conditions, number of slices and resolution have to be set.

Automated Ion Milling & Image Acquisition

The first step in the preparation consists of creating an optional protective layer, milling a ditch of the given depth, and, preparing a polished initial cross-section. The ditch size is automatically set in order to prevent esti­mated redeposition effects and geometrical shadowing of the cross-section. A protective Pt layer is deposited in some cases, e.g. when a precise surface profile reconstruction is required, and in other cases can be switched off. The second step starts from the initial cross-section. A sequen­tial process of milling away thin slices of material followed by SEM image acquisition. The tilt correction, image shift and focus are automatically re-adjusted in order to keep the image of the polished surface at the centre of the view field. The whole process of data acquisition for a volume of approx. 10 × 10 × 10 μm3 can take about 2-3 hours (depending on the selected milling conditions).

Data Post-Processing

The acquired series of images are not always suited for a direct visualization without post-processing. This is why the images can be cropped, realigned and some additional filters can be applied (shading correction, median, etc.).

3D Visualization

Various visualization methods are available. The module can load a series of grayscale images or import raw binary data (dimensions, scale and file format are given by the user).

There are several visualization methods:


Multiple isosurfaces of different colours and transparencies can be shown. High-quality images are required for this method (low noise).

Direct volume rendering

In direct volume rendering the colour and opacity depends on the brightness value in the image. This algorithm is not so sensitive to noise or gradual changes in brightness as the isosurfaces method.


Multiple slices can be displayed, either aligned to a major axis or taken at arbitrary angles. A different colour map (palette) can be attached to each slice. The slices can be opaque, transparent to a given threshold or their transparency can be defined in the colour map.

Ultra-Fast 3D EDS and 3D EBSD Microanalysis on the FERA Xe+ Plasma FIB-SEM
In this application example a first results of ultra-fast 3D EBSD and 3D EDS done on FERA FIB-SEM are shown. The three dimensional material microanalysis became a popular analytical method during the past few years, gaining from the ability to describe the material structure and composition as it exists in real components. A high resolution scanning electron microscope (SEM) combined with a focused ion beam (FIB) is used for a high precision tomographical method based on FIB slicing and SEM observation of the slice. The FIB-SEM can be further equipped by analytical methods like energy-dispersive X-ray spectrometer (EDS) for elemental composition or electron backscattered diffraction analyzer (EBSD) for crystal orientation mapping, resulting in 3D microanalysis, i.e. 3D EDS and 3D EBSD. However, the main limitation of this tomographic method so far has been the speed of data acquisition. This influences also the volume which can be analyzed in reasonable time of several hours.
