Abstract:
1. A pattern correction method of, when a plurality of pattern elements on a mask used to process line patterns formed on a substrate are transferred to the substrate, performing proximity effect correction of a pattern element, among the plurality of pattern elements, so that a transferred image has a target dimension, the method comprising the steps of: setting, based on a density of pattern elements in a peripheral region surrounding a pattern element of interest, among the plurality of pattern elements, a dimension of a pattern element whose transferred image formed under the density of the pattern elements in the peripheral region surrounding the pattern element of interest has the target dimension as a reference value for the pattern element of interest; calculating a dimension of transferred image of the pattern element of interest while changing a dimension of the pattern element of interest around the reference value; and determining the dimension of the pattern element of interest based on the calculation result.
