发明名称 Pattern-clip-based hotspot database system for layout verification
摘要 One embodiment of the present invention provides a system that generates a pattern-clip-based hotspot database for performing automatic pattern-clip-based layout verification. During operation, the system receives a list of pattern clips which specify manufacturing hotspots to be avoided in a layout, wherein each pattern clip comprises a set of geometries in proximity to each other. Next, for each pattern clip, the system perturbs the pattern clip to determine a first range of variations for the constituent set of geometries wherein the perturbed pattern clip no longer causes a manufacturing hotspot. The system then extracts a set of correction guidance descriptions from the first range of variations for correcting the pattern clip. Subsequently, the system stores the pattern clip and the set of correction guidance descriptions in the pattern-clip-based hotspot database.
