Abstract:
A scanning exposure apparatus for transferring a pattern of a master onto each of a plurality of shot regions defined on a substrate, while synchronously scanning the master and the substrate, said apparatus comprising:a master stage for moving the master; a substrate stage for moving the substrate; and a controller for controlling movement of said substrate stage during scanning exposure of the plurality of shot regions so as to assure that a setting distance in which said substrate stage is moved guarantees that a synchronization error between said master stage and said substrate stage falls within an allowable range after said substrate stage is accelerated up to a scan speed for the scanning exposure, wherein said controller controls the movement of said substrate stage such that a setting distance for a first shot region, which is exposed first, upon a change in a row to which a shot region to be exposed belongs, is set to be longer than a setting distance for other shot regions.
