Patent ID: 8390779

Claim:
An exposure apparatus which exposes a substrate, comprising: an optical system which includes a plurality of optical elements, 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, the second pattern being different from the first pattern; a first detecting system which obtains at least one of position information about the image of the first pattern to be formed in the first exposure area and position information about the image of the second pattern to be formed in the second exposure area; and a reference which is arranged on a light-exit side of an optical element of the plurality of optical elements, the optical element being arranged closest to the first exposure area or the second exposure area; wherein a predetermined area on the substrate is subjected to multiple exposure with the image of the first pattern formed in the first exposure area and the image of the second pattern formed in the second exposure area; the first detecting system detects at least one of a first positional relationship between the first pattern and the reference and a second positional relationship between the second pattern and the reference, via at least a part of the optical system; and at least one of the position information about the image of the first pattern to be formed in the first exposure area and the position information about the image of the second pattern to be formed in the second exposure area is obtained based on a detection result of the first detecting system and thereby a positional relationship between the first pattern and the second pattern is adjusted.
