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.
