Abstract:
1. A manufacturing method for a photomask based on design data indicating a plurality of sides of a first figure element comprising the steps of; extracting first data from the design data indicating a side of a first figure element; assigning identical first identification data to identical first data indicating the side of a first figure element; configuring a side group from the side of a first figure element and sides of a first figure element within a constant distance of the side of a first figure element; assigning identical second identification data to an identical side data group indicating the side group; estimating an influence of an optical proximity effect on the side group; generating second data indicating a side of a second figure element for compensating the influence of the optical proximity effect on the side group; configuring figure data indicating a plurality of sides of a second figure element by assigning identical second data to the first data, the first data being included in the identical side data group with identical second identification data; and forming photomask patterns on the photomask from the figure data.
