摘要
An optical proximity correction (OPC) method is disclosed, in which original design patterns are first grouped into a first group and a second group, wherein each pattern of the first group has a size greater than a size of any pattern of the second group. Next, a simple OPC model and a complex OPC model are individually established for the two groups using different numbers of convolution kernels. After that, the simple OPC model and the complex OPC model are combined together to generate a hybrid OPC model which is thereafter used to perform an OPC treatment on the original design patterns. This method is capable of shortening the OPC processing time and increasing the flexibility in utilizing OPC software and hardware resources.
