Abstract:
1. A method, in a data processing system, for electrical yield enhancement retargeting of photolithographic layouts, the method comprising: performing, by an electrical yield enhancement retargeting mechanism in the data processing system, optical proximity correction on a set of target patterns in order to produce a set of optical proximity correction mask shapes; generating, by the electrical yield enhancement retargeting mechanism, a set of lithographic contours for each of the set of optical proximity correction mask shapes; determining, by the electrical yield enhancement retargeting mechanism, electrical yield sensitivities for at least one shape in a set of shapes in the set of target patterns; determining, by the electrical yield enhancement retargeting mechanism, an amount and a direction of retargeting for each of the at least one shape in the set of shapes based on the electrical yield sensitivity of the shape, wherein the amount and the direction of retargeting for each shape is determined by the method comprising: wherein −a is the negative distance away from the initial edge associated with the negative lithographic variation in the shape, wherein k generating, by the electrical yield enhancement retargeting mechanism, a new set of target patterns with retargeted edges for each shape in the at least one shape based on the amount and the direction of retargeting.
