Curvilinear Mask Optimization for Inverse Lithography Based on B-splines and Delaunay Triangulation
Xiaoru Yi, Junqing Chen
In this paper, we propose a novel gradient-based method to optimize curvilinear masks in optical lithography. The mask pattern is represented by periodic B-spline curves. We apply…
