Patent ID: 7079221

Claim:
An exposure apparatus for exposing a substrate to light directed via an original, said apparatus comprising: an original stage configured to hold the original and to move; a substrate stage configured to hold the substrate and to move; a reference mark arranged on said original stage and configured so that a positional relationship between said original stage and said substrate stage is measured; an alignment mark pattern arranged on said original stage and configured to be imaged on the substrate to form an alignment mark on the substrate, said alignment mark pattern having a known position relative to said reference mark; a projection optical system configured to direct light from a selected one of a pattern of the original and said alignment mark pattern, and to image the selected one on the substrate; an alignment scope configured to detect the alignment mark formed on the substrate; a processor configured to obtain a position of the alignment mark based on a detection by said alignment scope; and a controller configured to control a position of said substrate stage based on a position of the alignment mark obtained by said processor, wherein said controller is also configured to control a position of said original stage and a position of said substrate stage so that said alignment mark pattern is imaged in a peripheral region of the substrate outside a region where the pattern of the original is to be imaged.
