Abstract:
An exposure apparatus that performs scanning exposure for a substrate is provided. The apparatus comprises a light source, a digital mirror device including a plurality of mirrors capable of controlling a direction of light emitted from the light source and configured to operate to adjust an integrated exposure amount on the substrate in accordance with scanning of the substrate, a projection optical system configured to guide light from the digital mirror device to the substrate and project a pattern onto the substrate, and a controller configured to control the plurality of mirrors in the digital mirror device based on the pattern to be projected onto the substrate, wherein the controller controls the plurality of mirrors such that an integrated exposure amount in an edge portion of the pattern becomes larger than an integrated exposure amount in a portion other than the edge portion.

Claim (Index 7):
An exposure method in an exposure apparatus that performs scanning exposure for a substrate,\n the exposure apparatus comprising a light source, a digital mirror device including a plurality of mirrors capable of controlling a direction of light emitted from the light source and configured to operate to adjust an integrated exposure amount on the substrate in accordance with scanning of the substrate, a projection optical system configured to guide light from the digital mirror device to the substrate and project a pattern onto the substrate, and a controller configured to control the plurality of mirrors in the digital mirror device based on the pattern to be projected onto the substrate, the method comprising: measuring, in advance, an integrated exposure amount of light reflected by each of the plurality of mirrors in the digital mirror device and guided to the substrate; determining ON/OFF of each of the plurality of mirrors in the digital mirror device based on a result of the measuring such that an integrated exposure amount in the pattern becomes uniform; correcting, based on a result of test exposure performed in accordance with a result of the determining, the result of the determining such that an integrated exposure amount in each spot in an edge portion of the pattern becomes larger than an integrated exposure amount in each spot in a portion other than the edge portion; and exposing the substrate in accordance with the corrected result.
