  • Patent number: 8122385
    Abstract: In a model-based OPC which makes a suitable mask correction for each mask pattern using an optical image intensity simulator, a mask pattern is divided into subregions and the model of optical image intensity simulation is changed according to the contents of the pattern in each subregion.
