Abstract:
1. A method of performing an optical proximity correction (OPC) procedure, comprising: forming an integrated chip (IC) design comprising a graphical representation of an integrated chip, wherein the IC design has an original design layer comprising one or more original design shapes; generating an approximation design layer from the original design layer, wherein the approximation design layer is different than the original design layer; and performing an optical proximity correction (OPC) procedure on the approximation design layer, by dissecting the approximation design layer into a plurality of separate edges and then selectively moving one or more of the separate edges in a direction perpendicular to the separate edge, to form an OPC'd layer that produces on-wafer shapes that correspond to the one or more original design shapes, wherein a computing device is used to form the IC design, to generate the approximation design layer, or to perform the OPC procedure on the approximation design layer.
