Abstract:
1. An energy beam exposure method using an energy beam exposure apparatus capable of controlling magnitude relation between a blur of an energy beam in a first direction and a blur of the energy beam in a second direction different from the first direction for exposing a pattern on a sample in the energy beam exposure apparatus, comprising: adjusting the magnitude relation of the blurs of the energy beam in the first and second directions so that the blur of the energy beam in one of the first and second directions is set smaller than the blur of the energy beam in the other of the first and second directions; adjusting the direction of the sample in the energy beam exposure apparatus on the basis of the pattern to be projected onto the sample and the magnitude relation of the blurs of the energy beam in the first and second directions; and projecting the pattern onto the sample by exposing the sample to the energy beam and using shape correction of the pattern, the shape correction being needed to compensate differences in the blurs of the energy beam in the first and second directions.
