Abstract
Critical location information is used for providing a critical location evaluation method for a semiconductor apparatus pattern. The critical location information includes coordinate information about the critical location and characteristic information indicating a thinning direction and a magnitude thereof at the critical location. Use of this evaluation method can accurately evaluate specification and analysis of thinning or a pattern which makes it difficult to pinpoint a critical location through the visual inspection.
