Patent ID: 8531649

Claim:
An exposure apparatus comprising: an illumination optical system configured to illuminate a reticle with light from a light source; a projection optical system configured to project a pattern of the reticle onto a substrate; a light shielding plate which is placed on a plane conjugate to an object plane of the projection optical system in the illumination optical system, includes, on an edge thereof, an arc that overlaps a circular boundary line inside an outer periphery of the substrate, and is configured to define a region on the substrate, to which the pattern is to be transferred; a driving unit configured to drive the light shielding plate in an outer peripheral shot region on the substrate; a detection unit configured to detect a shift amount between the center position of the substrate and the center position of an array of a plurality of shot regions on a layer formed on the substrate; and a control unit configured to, in exposing the outer peripheral shot region, perform first control in which the control unit controls the driving unit so that the light shielding plate is positioned at a position, at which the light shielding plate shields light incident on an outer peripheral region shifted inward from the outer periphery of the substrate by a predetermined width, based on the shift amount detected by the detection unit.
