Optical proximity correction opc
WebOptical proximity correction (OPC) is one of the most widely used resolution enhancement techniques (RET) in nanometer designs to improve subwavelength printability. Conventional model-based OPC assumes nominal process parameters without considering pro-cess variations, due to prohibitive runtimes of lithography simula-tions across process windows. WebThe optical proximity correction tool 500 may further perform mask process correction (MPC) on the processed layout design. Although the photomask features are typically …
