    摘要: According to a mask defect inspection data generating method, a distance between inspection areas neighboring in a predetermined direction is calculated based on inspection area control information defined in photomask inspection data. It is determined whether or not the calculated distance between inspection areas is less than a predetermined distance. When it is determined that the distance between inspection areas is less than a predetermined distance, the inspection area is combined to produce an optimization inspection area. The produced optimization inspection area information is defined in inspection layout data for making a reference in die-to-database defect inspection.
