Abstract:
1. A manufacturing method for a photomask based on design data indicating plurality of first figure elements comprising the steps of; extracting first data from design data indicating a first figure element; assigning identical first identification data to a identical first data indicating the identical shape of first figure element; establishing a region based on the first figure element; recognizing a first figure element group in the region by the identical first identification data; configuring a first data group indicating the first figure element group being in the region; assigning identical second identification data to a identical first data group; estimating a influence of an optical proximity effect on the first figure element group; generating second data indicating a second figure element for compensating the influence of the optical proximity effect on the first figure element group; 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 in the region, the identical first data group having identical second identification data; forming photomask patterns on the photomask using the figure data.
