| Summary | This technology consists of two convolutional neural networks (CNNs): LithoNetOPCNet. LithoNet mimics the fabrication procedure, involving lithographyetching, to predict the shape of a fabricated IC circuitry given an input layout. OPCNet, in cooperation with a pre-trained LithoNet, mimics the optical proximity correction procedure used to correct the layout designgenerate a modif |

| Scientific Breakthrough | This technology is the first to use a deep neural network to accurately model the effect of lithographyetching processes on the shape deformation of a fabricated IC circuitry. It can also generates a correct mask pattern so that the fabricated IC circuitry will have a shape close to a desired pattern. The technolgy can lead to a paradigm shift of IC design for manufacturability. |
