Patent ID: 8659740

Claim:
An exposure apparatus comprising: a projection optical system, including a first optical element and a second optical element, configured to project a pattern of a reticle onto a substrate; a driving unit configured to drive the first optical element in a first direction so as to adjust one of symmetrical aberration and asymmetrical aberration about an optical axis of the projection optical system and to drive the second optical element in a second direction so as to adjust the other aberration; a detecting unit configured to detect a driving error which occurs in the second direction when said driving unit drives the first optical element in the first direction; and a control unit configured to control said driving unit to drive the first optical element in the first direction by a first driving amount calculated based on an aberration of the projection optical system, drive the second optical element in the second direction by a second driving amount calculated based on the other aberration, and drive the second optical element in the second direction by a third driving amount calculated based on the driving error detected by said detecting unit when the first optical element is driven in the first direction by the first driving amount.
