Abstract:
The present invention provides an exposure apparatus which transfers a pattern of a mask onto a substrate by exposing the substrate while scanning the mask and the substrate, the apparatus including a stage configured to hold the substrate and move, a control unit configured to control movement of the stage, a first measurement unit configured to measure a position, in a height direction, of a shot region of the substrate held by the stage before the shot region reaches an exposure area where the shot region is exposed, and a second measurement unit configured to measure the position of the shot region in the height direction prior to the first measurement unit.

Claim (Index 14):
The apparatus according to  claim 11 , wherein the control unit:\n performs low-pass filter processing having a cutoff frequency on each of first difference data between the final target position and the position of the shot region in the height direction measured by the second measurement unit, and second difference data between the final target position and the position of the shot region in the height direction measured by the first measurement unit to generate control data for controlling driving of the stage in the height direction; and makes the cutoff frequency of the low-pass filter processing performed on the first difference data higher than the cutoff frequency of the low-pass filter processing performed on the second difference data.
