Abstract:
According to one embodiment, there is provided an exposure apparatus which projects a pattern of an original onto a substrate by a projection optical system so as to expose the substrate. The exposure apparatus includes a substrate stage, an alignment detecting system, and a controller. The substrate stage holds the substrate on which shot areas each including multiple chip areas are placed. The alignment detecting system detects multiple first alignment marks placed in a peripheral region in a first chip area in the shot area. The controller obtains the first amount of positional deviation for the first chip area according to results of detecting the multiple first alignment marks and controls exposure conditions for the first chip area in the shot area according to the first amount of positional deviation.

Claim (Index 3):
The exposure apparatus according to  claim 2 , wherein\n the exposure apparatus is a scanning exposure apparatus which projects the pattern of the original onto the substrate by the projection optical system so as to expose the substrate while relatively scanning the original and the substrate, and wherein the second chip area is shifted in position in a scan direction relative to the first chip area in the shot area, and the controller performs at least one of correcting projection magnification of the projection optical system, correcting relative scan speed of the original and the substrate, correcting an inclination of the substrate relative to the original, and correcting a rotation angle of the substrate relative to the original according to the first amount of positional deviation during respective of a first period and a second period in the exposure time for the shot area, the first period being a period when an area corresponding to the first chip area is scanned, the second period being a period when an area corresponding to the second chip area is scanned.
