ABSTRACT:
A scanning exposure apparatus includes a projection optical system which projects a pattern formed on a mask onto an object, a stage which holds an object and moves in a direction perpendicular to an optical axis of the projection optical system, a measurement system which measures a position of a surface of the object in a direction of the optical axis in response to a reset signal, and a generation system which generates the reset signal when the stage arrives at each predetermined position in the direction perpendicular to the optical axis.
