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. Web1998. Abstract. In this thesis, we first look at the Optical Proximity Correction (OPC) problem and define the goals, constraints, and techniques available. Then, a practical and …
WebA solution for performing an optical proximity correction (OPC) process on a layout by incorporating a critical dimension (CD) correction is provided. A method may include separating the layout into a first portion and a second portion corresponding to the two exposures; creating a model for calculating a CD correction for a site on the first portion, …
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.
