    摘要: A method of forming a layout of a photomask using optical proximity correction (OPC) includes: receiving a layout of a mask pattern; obtaining image parameters of a two-dimensional (2D) layout mask from a simulation; obtaining image parameters of a three-dimensional (3D) layout mask from a simulation; obtaining differences between the image parameters of the 2D and 3D masks; and performing optical proximity correction (OPC) on the 2D mask to compensate for the differences between the image parameters of the 2D and 3D masks by using a visible kernel with respect to the 2D mask.
