Masque README

Masque is a Python module for designing lithography masks.

The general idea is to implement something resembling the GDSII file-format, but with some vectorized element types (eg. circles, not just polygons), better support for E-beam doses, and the ability to output to multiple formats.

Installation

Requirements:

  • python >= 3.5 (written and tested with 3.6)
  • numpy
  • matplotlib (optional, used for visualization functions and text)
  • python-gdsii (optional, used for gdsii i/o)
  • svgwrite (optional, used for svg output)
  • freetype (optional, used for text)

Install with pip:

pip3 install masque

Alternatively, install from git

pip3 install git+https://mpxd.net/code/jan/masque.git@release

TODO

  • Mirroring
  • Polygon de-embedding

Maybe

  • Construct from bitmap
  • Boolean operations on polygons (using pyclipper)
  • Output to OASIS (using fatamorgana)
