Patent ID: 8364437

Claim:
A method of inspecting a mark arrangement for inspecting an arrangement state of mark data corresponding to a mark in mask data for manufacturing a mask including the mark for alignment or measurement formed on a scribe line of a process target, the method comprising: generating, by a processor, mark seed data that includes an inspection mark that includes vector information for detecting a rotation in units of a predetermined angle or a mirroring of the mark and that is not drawn on the mask, and the mark data; generating, by a processor, the mask data in which the mark seed data is arranged on the scribe line of the mask; calculating, by a processor, coordinates of the inspection mark from a reference position set to the mask data for each of the mark seed data in the mask data; detecting, by a processor, an arrangement state of the inspection mark with respect to the reference position by using calculated coordinates and the vector information on the inspection mark; and judging, by a processor, whether the mark seed data is correctly arranged on the scribe line by comparing the arrangement state of the inspection mark with an arrangement check rule that defines an arrangement state of the mark seed data on the mask, wherein the inspection mark is a first inspection mark that includes a first point in the mark seed data and a second point that is shifted by a distance s with fixed value in a first direction and by a distance t with fixed value in a second direction that is vertical to the first direction from the first point so that conditions of |s|≠|t|, s≠0, and t≠0 are satisfied, and the first point and the second point include identification information for identifying the first point and the second point as attribute information in addition to information on a layer arranged.
