摘要: A method of correcting a design pattern of a mask takes into account the overlay margin between adjacent one of actual patterns that are stacked on a substrate. First, a pattern of a photomask for forming a first one of the actual patterns on a substrate is conceived. Also, information representing the image of a second one of the actual patterns is produced. Then, optical proximity correction (OPC) is performed on the first pattern based on the information. The information may be obtained by simulating the transcription of a photomask having a second pattern designed to form the second actual pattern, or by forming the second actual pattern and then capturing the image of the second actual pattern. Accordingly, a sufficient margin is provided between the second actual pattern and the first pattern on which the optical proximity correction has been performed.
