Original Abstract Submitted

A method of making a semiconductor device includes forming at least one fiducial mark on a photomask. The method further includes defining a pattern including a plurality of sub-patterns on the photomask in a pattern region. The defining the pattern includes defining a first sub-pattern of the plurality of sub-patterns having a first spacing from a second sub-pattern of the plurality of sub-patterns, wherein the first spacing is different from a second spacing between the second sub-pattern and a third sub-pattern of the plurality of sub-patterns.
