Abstract:
1. A scanning type exposure apparatus for transferring a pattern on a mask onto a substrate by synchronously moving the mask and the substrate, the apparatus comprising: a base board; a first movable member which holds the substrate, the first movable member being movable relative to the base board; a second movable member which arranges the first movable member thereon, the second movable member being arranged on the base board to move relative to the base board and the first movable member respectively; a driving system which drives the second movable member; and a control unit which varies control response of the driving system in a plurality of operation processes including a scanning exposure operation process for the substrate respectively, wherein; the control unit sets the control response of the driving system so that a relative position of the second movable member with respect to the base board is substantially maintained during the movement of the first movable member in a non-scanning direction after the scanning exposure; and the control unit sets a response frequency of the driving system to be higher than that during the scanning exposure, when the first movable member is moved in the non-scanning direction after the scanning exposure.
