Abstract:
1. A method for manufacturing a semiconductor device or a photomask, the method being executed by an exposure device, the method comprising: extracting a first pattern that exists within a range of a first distance to a boundary of first and second deflection regions, the first pattern being in the first deflection region and using exposure data stored by the exposure device; searching a second pattern that is adjacent to the first pattern and in the second deflection region different from the first deflection region, using the exposure data that is included; and performing first data processing using the exposure data when the pattern width of the first pattern is a first width or more, the first data processing including: performing second data processing using the exposure data when the pattern width of the first pattern is less than the first width but greater than or equal to a second width, the second data processing including: performing third data processing using the exposure data when the pattern width of the first pattern is less than the second width, the third data processing including: exposing a pattern on the semiconductor device or a photomask by using exposure data that is obtained by the first data processing, the second data processing or the third data processing while scanning the first and second deflection regions, determined depending on a deflection width of an exposure device on an exposure target with electron beams emitted from the exposure device.
