Abstract

A pattern generation method includes changing a dimension of a pattern included in each mesh-like region of a plurality of mesh-like regions by using an area of the pattern and a total sum of lengths of circumferential sides of the pattern included in each mesh-like region to correct a dimension error of the pattern, wherein the dimension error being caused by loading effects and the plurality of mesh-like regions being virtually divided from a pattern forming region of a target object, and generating a pattern of the dimension changed on the target object.
