Paper Abstract

The traditional Hopkins based microlithography aerial image simulation methods most likely require expensive 4D Singular Value Decomposition operations to obtain mutually incoherent kernels. This is often a problem when the requirement of resolution is high especially when sub-resolution assist features are present. During the process development and model fitting, kernels are required to generate frequently. In this paper, we demonstrate that it is not necessary to perform this expensive task to generate those kernels. By taking advantage of several classical matrix theories, we are able to directly extract kernels without resorting to 4D Singular Value Decomposition operations. The accuracy and efficiency will be extensively studied in the experimental results.
