Patent ID: 8022376

Claim:
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: dividing the first pattern into an edge portion and an inner portion, and moving the boundary of the first deflection region to inside of the first pattern by changing registration of the edge portion of the first pattern on the existing side of the adjacent second pattern within the range of the first distance to the second deflection region of the second pattern; 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: dividing the first pattern into the edge portion and the inner portion, performing double-registration for the edge portion of the first pattern, to the first and second deflection regions, the edge portion being on the existing side of the adjacent second pattern within a second distance, so that double-exposing is performed about the edge portion, and setting the amounts of exposure of the edge portion of the first pattern in the first and second deflection regions to half; 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: performing double-registration for the first pattern and the adjacent second pattern, to the first and second deflection regions, the adjacent second pattern being within the second distance, so that double-exposing is performed about the first pattern and the adjacent second pattern, and setting the amounts of exposure of the first pattern and the adjacent second pattern in the first and second deflection regions to half; and 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.
