8 December 1995 Simplified rule generation for automated rules-based optical enhancement
Author Affiliations +
This paper demonstrates a new methodology called parametric anchoring in which a small number of representative line-space measurements are used to match a given lithographic process to computational models for a rule-based optical enhancement scheme. The rule generation program, SimRuleTM, which incorporates the models, is used to create the rule lookup tables which are in turn used by the rules-based correction program, OPRXTM. Parametric anchoring is performed before the rule tables are computed, as distinguished from the earlier anchoring approach in which the multi-dimensional rule tables are reshaped to match a number of measured points. Parametric anchoring uses line and space measurements which are familiar to process engineers.
