发明名称 SYSTEM AND METHOD OF PREDICTING PROBLEMATIC AREAS FOR LITHOGRAPHY IN A CIRCUIT DESIGN
摘要 A system and method is provided which predicts problematic areas for lithography in a circuit design, and more specifically, which uses modeling data from a modeling tool to accurately predict problematic lithographic areas. The method includes identifying surface heights of plurality of tiles of a modeled wafer, and mathematically mimicking a lithographic tool to determine best planes of focus for exposure for the plurality of tiles.
