DC2-NPGS (DesignCAD)

The Nanometer Pattern Generation System (NPGS) is a Scanning Eletron Microskope (SEM ) lithography system. The objective for NPGS is to provide a powerful, versatile, and easy to use system for doing advanced electron beam lithography or ion beam lithography using a commercial SEM (Scanning Electron Microscope), STEM (Scanning Transmission Electron Microscope), FIB (Focused Ion Beam), dual beam (SEM/FIB), or Helium Ion microscope. It is shiped with a software DesignCAD, which produces the required input data. The associated file format is DC2. However the NPGS system just uses a subset of possible entities.

The LayoutEditor can read and write the DC2 format. The supported entities are identical to the entities supported by the NPGS, so that generated files can directly used and existing files can be checked on its appearance after exposure.

DC2-NPGS file format

The DC2-NPGS file format does not support hierarchy. So a flat copy of the current drawing is saved. Also text elements are not supported and not saved. DC2-NPGS files are ASCII text files mostly using numbers. Here is an example of an DC2-NPGS file:
