Focused Ion Beam Bitmap File Generator

We present a graphical user interface developed in Python that facilitates the generation of bitmap files for the fabrication of patterns and arrays of different geometries with a Focused Ion Beam (FIB) taking into account different milling parameters. For 3D structures, a suitable grayscale can be generated depending on the profile function defined. A second window will show the cross-section view of the structure. The patterns generated with the interface can be saved as a 24-bit bitmap file and then imported into the FIB system.
