Optical and process correction
WebDescription Optical proximity correction (OPC) is often associated with a photomask. The photomask is produced in a photomask facility. In the flow, a chipmaker designs an IC, which is then translated into a file format. Then, a photomask is developed based on that format. A photomask is a master template for a given IC design.
