An exposure apparatus includes a projection 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; and 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 shot 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 projection optical system. The substrate can be subjected to the multiple exposure satisfactorily and efficiently.
An exposure apparatus which exposes a substrate, comprising:
An exposure method for performing multiple exposure for a predetermined area on a substrate with an image of a first pattern and an image of a second pattern by illumination of the first pattern and illumination of the second pattern, the exposure method comprising:
