Patent ID: 8472009

Claim:
An exposure apparatus which projects a pattern of an original onto a substrate by a projection optical system to expose the substrate, the apparatus comprising: a measurement device configured to perform a measurement using an original-side fiducial plate arranged on one of the original and the original stage, and a substrate-side fiducial plate arranged on the substrate stage; and a controller configured to control the projection optical system, the original-side fiducial plate including a first original-side mark and a second original-side mark, and the substrate-side fiducial plate including a first substrate-side mark and a second substrate-side mark, the measurement including a first measurement performed using the first original-side mark and the first substrate-side mark while moving the substrate-side fiducial plate in a direction of the optical axis of the projection optical system, and a second measurement performed using the second original-side mark and the second substrate-side mark while moving the substrate-side fiducial plate in the direction of the optical axis of the projection optical system, wherein the controller is configured to control imaging characteristics of the projection optical system associated with a direction perpendicular to the optical axis of the projection optical system so that the first measurement and the second measurement can be performed simultaneously, and to cause the measurement device to perform the first measurement and the second measurement simultaneously after controlling the imaging characteristic by the controller.
