| 摘要 |
An exposure mask pattern correction method comprises preparing a unit process group which includes a plurality of unit processes to form a pattern on a substrate by using an exposure mask, the plurality of unit processes including a unit process concerning manufacture of the exposure mask, a unit process concerning lithography using the exposure mask, and a unit process concerning etching of the substrate, setting a correction rule/model to perform an optical proximity effect correction for the exposure mask by using first and second optical proximity effects data when a change is arisen in at least one of the plurality of unit processes, the first and second optical proximity effect data being data respectively concerning an optical proximity effect caused by the at least one unit process before and after the change, and performing the optical proximity effect correction for the exposure mask by using the correction rule/model. |
