fib-o-mat#

A Python toolbox to generate focused ion beam patterning layouts#

_images/flowchart.png

fib-o-mat is a Python library to create beam patterns for focused ion beam (FIB) instruments.

Features:

  • built-in modeling of patterning geometries

  • customizable rasterization styles

  • optimization of patterning geometries and rasterized patterns

  • extendable

Pattern geometries can be modeled directly in Python based on (pre-)defined geometric primitives or imported from vector graphics. They can be equipped with beam and rasterization settings and exported to microscope-compatible files.

fib-o-mat is designed to be flexible and easily expandable. Hence, adding support for different microscopes, custom geometric primitives or optimization routines is a straightforward process.

To use fib-o-mat, basic Python knowledge and a good understanding of the target microscope are required.

Getting started

Install fib-o-mat and create your first patterning layout.
