Abstract

An optical proximity correction system for local correction of an aerial image produced from a mask having transmissive portions and blocking portions collectively defining a target design includes an analyzer to match one or more segments of the target design to one or more typical case segments from a predetermined set of typical case segments; a controller, coupled to the analyzer, for approximating each of the one or more segments of the target design with matching typical case segments from the set of typical case segments to produce an adjusted aerial image. The method for optical proximity correction using local correction of an aerial image produced from a mask having transmissive portions and blocking portions collectively defining a target design, includes: a) analyzing the target design to produce one or more segments from the target design and to match the one or more segments to one or more typical case segments from a predetermined set of typical case segments; and b) approximating each of the one or more segments of the target design with the matching typical case segments from the set of typical case segments to produce an adjusted aerial image.
