An exposure apparatus and a fabrication method thereof include an obtaining unit configured to obtain data of a first imaging position at which light from a first pattern having, as a longitudinal direction thereof, a first direction perpendicular to an optical axis of a projection optical system forms an image via the projection optical system, and data of a second imaging position at which light from a second pattern having, as a longitudinal direction thereof, a second direction which is not parallel to the first direction and is perpendicular to the optical axis forms an image via the projection optical system, when the first pattern and the second pattern are respectively placed on an object plane of the projection optical system, and a control unit configured to control a stage so that a substrate is positioned at a target position of the substrate along the optical axis. |
