Abstract:
1. A scan the exposure apparatus for transferring a pattern onto a substrate by scan exposure, said apparatus comprising: a stage for moving the substrate in a Y direction corresponding to a scan direction, and in an X direction intersecting the scan direction; an alignment scope for performing measurement for alignment of the substrate, at a position spaced, in the Y direction, from a position where the exposure of the substrate is to be carried out, said alignment scope being disposed on a straight line parallel to a Y-axis and passing through the position for exposure of the substrate; an X measuring device for performing yaw measurement of said stage by use of an X reflection surface provided on said stage along the Y direction; a Y measuring device for performing yaw measurement of said stage by use of a Y reflection surface provided on said stage along the X direction; and a controller which selects yaw measurement information of said X measuring device for an alignment operation including the alignment measurement using said alignment scope, and which selects yaw measurement information of said Y measuring device for the scan exposure.
