Abstract:
Methods and systems for design of integrated circuits including performing OPC are discussed. In one embodiment, design data having a geometric feature is provided. A base feature is formed from the geometric feature, which has a substantially linear edge. A pseudo dissection point is determined on the base feature. Add or trim a polygon from the base feature to form a modified feature. An OPC process is performed on the modified feature to generate an output design. The output design is used to fabricate a semiconductor device on a semiconductor substrate.
