Integrated circuit design pattern`s structural components geometry optimization method for producing photomask, involves optimizing geometries of structural components and inserting optimized base patterns into circuit design

摘要

The method involves dividing a pattern of a circuit design iteratively, into corresponding base patterns, to classify the parts of the pattern into the structural components which complies with the base patterns. Further base patterns are provided for the parts which are not classified. The geometries of the structural components are optimized and the optimized base patterns are inserted into the circuit design. An independent claim is also included for a use of a structural component geometry optimizing method for the production of a photomask.
