Webniques RETs such as optical proximity correction OPC and phase-shift masks PSMs are applied to an increasing number of mask layers and with increasing aggressiveness. The recent steep increase in mask costs and lithographic complexity due to these RET approaches has had a harmful impact on design starts and project risk across the semicon- 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.
