Abstract:
A scanning type exposure apparatus, comprising:a substrate stage for holding a substrate and for moving the substrate in a scanning direction and at least one substrate stage rotational direction; an original stage for holding an original, the original having a pattern thereon, and for moving the original in the scanning direction and at least one original stage rotational direction; and a controller for controlling movements of said substrate stage and said original stage, wherein during a scanning exposure of the substrate said controller controls driving of a scanning direction driver of said original stage synchronously with the driving of a scanning direction driver of the substrate stage, while controlling driving of a rotational movement driver of said substrate stage in the at least one substrate stage rotational direction and driving of a rotational movement driver of said original stage in the at least one original stage rotational direction during the scanning exposure independently of the synchronously controlled driving of the scanning direction drivers of the substrate stage and the original stage in the scanning direction, wherein said controller controls the rotational movement driver of said substrate stage independently of the rotational movement driver of said original stage.
