A scanning exposure apparatus includes a projection system, a stage system, a first detector and a control system. The stage system has first and second stages, each of which is movable independently in a plane while holding a substrate. The first detector detects focusing information of a vicinity of an outer circumference of the substrate during a detecting operation. The control system controls the stage system to perform the detecting operation with the first stage, while performing a first exposure operation on the substrate held by the second stage. After the first exposure operation, a second exposure operation for the substrate held on the first stage is performed, in which a shot area in the vicinity of the outer circumference of the substrate is exposed by moving the first stage while adjusting a position of the substrate surface held by the first stage using the detected focusing information.
