Optical proximity correctionとは
WebOptical Proximity Correction (OPC) is one of the most important techniques in today's optical lithography based manufacturing process. Although the most widely used model-based OPC is expected to achieve highly accurate correction, it is also known to be extremely time-consuming. This paper proposes a regression model for OPC 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-
