    摘要： Disclosed is a method of manufacturing a photo mask comprising preparing mask data for a mask pattern to be formed on a mask substrate, calculating edge moving sensitivity with respect to each of patterns included in the mask pattern using the mask data, the edge moving sensitivity corresponding to a difference between a proper exposure dose and an exposure dose to be set when a pattern edge varies, determining a monitor portion of the mask pattern, based on the calculated edge moving sensitivity, actually forming the mask pattern on the mask substrate, acquiring a dimension of a pattern included in that portion of the mask pattern formed on the mask substrate which corresponds to the monitor portion, determining evaluation value for the mask pattern formed on the mask substrate, based on the acquired dimension, and determining whether the evaluation value satisfies predetermined conditions.
