    摘要: A pattern evaluating method includes generating a proximity pattern that affects a resolution performance of a circuit pattern around a lithography target pattern of the circuit pattern to be formed on the substrate, generating distribution information on a distribution of an influence degree to the resolution performance of the circuit pattern by using the lithography target pattern, calculating the influence degree to the resolution performance of the circuit pattern by the proximity pattern as a score by comparing the distribution information with the proximity pattern, and evaluating whether the proximity pattern is placed at an appropriate position in accordance with the circuit pattern based on the score.
