Abstract:
A scanning exposure apparatus for transferring a pattern of a master to a substrate with slit-shaped exposure light while a master stage holding the master and a substrate stage holding the substrate are moved, comprising:a measurement unit arranged to measure positional sync deviations between said master stage and said substrate stage with respect to each of a plurality of points in an exposure shot region on the substrate during scanning exposure of each of the plurality of points to the light; a first calculation unit arranged to calculate a standard deviation of the positional sync deviations measured by said measurement unit with respect to each of the plurality of points in the exposure shot region; a second calculation unit arranged to calculate a variation of the standard deviations calculated by said first calculation unit with respect to the exposure shot region; and a process unit arranged to execute a process based on the vibration calculated by said second calculation unit.
