WebThere are special cases of input features that would result in invalid (zero-area) output polygons. In these cases, a small value derived from the input feature XY Tolerance will be used as the width, length, or diameter to create output polygons. These polygons serve as 'place holders' for keeping track of features.

This plugin has been developed mainly for de-manhattanization of photonic structures.
WebFeb 3, 2024 · A good solution is to define a large rectangle and use the boolean operations in (e.g.) KLayout to subtract all structures from it. The DRC engine in KLayout is an excellent tool to automate this if needed. Another solution could be to let the mask manufacturer take care of the inversion.
