ABSTRACT:
A method of determining a photo mask, includes specifying a mask pattern for a photo mask for a first exposure apparatus, specifying a plurality of exposure conditions allowed to be set for a second exposure apparatus, predicting a projection image of the mask pattern to be projected on a substrate by the second exposure apparatus, for each of the exposure conditions, predicting a processed pattern to be formed on a substrate surface on the basis of the projection image, for each of the exposure conditions, determining whether or not the processed pattern meets a predetermined condition for each of the exposure conditions, and determining that the photo mask is applicable to the second exposure apparatus if the processed pattern meets the predetermined condition for at least one of the exposure conditions.
