Abstract:
1. An exposure apparatus which exposes a plurality of areas where peripheral parts partially overlap on a sensitive object with an energy beam, said exposure apparatus comprising: an illumination system having an optical axis perpendicular to a predetermined plane on which a pattern is placed, that illuminates the pattern with the energy beam and includes a changing device on the optical axis which changes an intensity distribution of the energy beam on a pupil plane of the illumination system so as to change an illumination condition of the pattern with the energy beam; a setting device provided in the illumination system, which defines a distribution of a cumulative amount of energy on one of the plurality of areas due to the exposure of the one area with the energy beam, the distribution having a slope portion at an overlapped peripheral part of the one area, in which the cumulative amount of energy is gradually decreased; and a correction device which corrects a change in a width of the slope portion caused by the change of the illumination condition.
