Patent ID: 8027020

Claim:
An exposure apparatus which exposes a substrate, comprising: an optical system which forms an image of a first pattern in a first exposure area and which forms an image of a second pattern in a second exposure area by illumination of the first pattern and illumination of the second pattern, the second pattern being different from the first pattern; an adjusting device which adjusts a surface positional relationship between a surface of the substrate and a first image plane for forming the image of the first pattern thereon and which adjusts a surface positional relationship between the surface of the substrate and a second image plane for forming the image of the second pattern thereon when a predetermined area on the substrate is subjected to multiple exposure with the image of the first pattern and the image of the second pattern via the optical system; an illumination system that illuminates the first pattern and the second pattern; and a control unit that is configured to control the illumination system, wherein the substrate is moved in a scanning direction with respect to the first exposure area and the second exposure area to make the predetermined area on the substrate pass across the first exposure area and the second exposure area during the multiple exposure for the predetermined area on the substrate, and the first pattern and the second pattern are moved in scanning directions respectively and the control unit controls the illumination system such that one of the illumination of the first pattern and the illumination of the second pattern is started and then the other of the illuminations is started before the one of the illuminations is completed during the multiple exposure for the predetermined area on the substrate.
