Abstract

A simulation package has been developed to address a wide variety of process latitude issues. The authors demonstrate its versatility by studying three examples: (i) process latitude degradation due to notching, (ii) line width dependence of a newly developed negative I-line chemically amplified resist on baking time, and (iii) linewidth control of an exposed x-ray 0.5 (mu) line as a function of baking time. A powerful all-purpose 3-D dissolution algorithm has been developed for this purpose. It is the only dissolution algorithm capable of handling changes to topology of the dissolution surface.
