  • Method and apparatus for identifying line-end features for lithography verification
    Patent number: 7194712
    Abstract: One embodiment of the invention provides a system that facilitates identifying line-end features in a layout for an integrated circuit. The system operates by first receiving the layout for the integrated circuit. Next, the system selects a polygon from the layout and marks a line-end seed on the polygon. The system then determines if the line-end seed is associated with a line feature, and if so, the system marks the line-end feature inside the line feature.
