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…

Mathematical and numerical study of a three-dimensional inverse eddy current problem
Junqing Chen, Ying Liang, Jun Zou
We study an inverse problem associated with an eddy current model. We first address the ill-posedness of the inverse problem by proving the compactness of the forward map with resp…
