    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.

    摘要: One embodiment of the present invention provides a system that automatically processes manufacturing hotspot information. During operation, the system receives a pattern clip associated with a manufacturing hotspot in a layout, wherein the pattern clip comprises a set of polygons in proximity to the manufacturing hotspot's location. Next, the system determines if the pattern clip matches a known manufacturing hotspot configuration. If the pattern clip does not match a known manufacturing hotspot configuration, the system then performs a perturbation process on the pattern clip to determine a set of correction recommendations to eliminate the manufacturing hotspot. By performing the perturbation process, the system additionally determines ranges of perturbation to the set of polygons wherein the perturbed pattern clip does not eliminate the manufacturing hotspot. Subsequently, the system stores the set of correction recommendations and the ranges of perturbation into a manufacturing hotspot database.
