Abstract:
1. An apparatus for performing a manufacturing method for photomask comprising; an unit for extracting first data from design data indicating first figure element; an unit for forming a first element group including the first figure element and first figure elements in a constant distance of the first figure element; an unit for assigning identical identification data to a identical first data group indicating the first figure element group; an unit for estimating a influence of an optical proximity effect on the first figure element group; an unit for generating second data indicating a second figure element for compensating the influence of the optical proximity effect on the first figure element group; an unit for configuring figure data indicating plurality of second figure elements by assigning identical second data to the identical first data being included in the identical first data group with the identical identification data; and forming photomask patterns on the photomask using the figure data.
