Zusammenfassung: | PROBLEM TO BE SOLVED: To improve drawing quality by forming a pattern with less visible ruggedness of an edge and suppressing generation of moire. SOLUTION: A spatial optical modulator (DMD 25) of a light beam irradiation device 20 comprises a plurality of mirrors arrayed in two directions orthogonal to each other. A drawing control unit 71 supplies drawing data at the same position in an exposure region a plurality of times to a drive circuit (DMD drive circuit 27) of the light beam irradiation device 20, and supplies a part of the drawing data supplied a plurality of times as a drawing data at a position adjoining to the exposure region to the drive circuit (DMD drive circuit 27) of the light beam irradiation device 20. A part of the light beam projected from the light beam irradiation device 20 is shifted to the position adjoining to the exposure region, which blurs an edge of the drawn pattern and makes ruggedness of the edge less visible. Further, the regularity of repeated feature of the pattern is disturbed, which suppresses generation of moire. COPYRIGHT: (C)2011,JPO&INPIT |
