Abstract:
An electron beam writing data creating device comprising:graphic data processing area split means for splitting design layout data for forming a plurality of graphic data processing areas each having redundant areas so that adjacent said graphic data processing areas are in contact with each other and said redundant area of each said graphic data processing area overlaps with adjacent said graphic data processing area;redundant part split means for splitting said design layout data into internal areas being defined in said graphic data processing areas by said outer peripheries of said redundant areas of said adjacent graphic data processing areas and redundant parts connecting all said redundant areas with each other;overlap removal means for removing overlap of graphic data in said internal areas and said redundant parts independently of each other; andredundant part removal means for removing overlap of said graphic data in said redundant parts on boundaries between said graphic data processing areas.
