Abstract
The present invention is directed to an optical proximity correction driven hierarchy. A method for constructing a hierarchy of optically independent structures for use in optical proximity correction of a circuit may include receiving an integrated circuit design, the design including geometric circuit elements for providing circuit functions of an integrated circuit. At least a portion of the integrated circuit design is exploded and geometric circuit elements of the exploded integrated circuit design are gathered into optically independent classes. A search is then performed for congruency for each optically independent class.
