Abstract:
A liquid crystal exposure apparatus has: scales arranged apart from each other in the X-axis direction provided at a substrate holder holding a substrate; heads irradiating the scales with a measurement beam from the heads that can move in the Y-axis direction; and a measurement device that measures position of the heads in the Y-axis direction. The apparatus has a measurement system which measures position of the substrate holder in directions of three degrees of freedom within a plane, based on measurement information of at least three heads and measurements of the measurement device. The heads move off of one scale while the substrate holder is moved in the X-axis direction and moves to irradiate another scale adjacent to the one scale, and correction information to control movement of the substrate holder is acquired using the heads moving to irradiate another scale, based on measurements of at least three heads.

Claim (Index 58):
The exposure apparatus according to  claim 54 , wherein\n the control system switches from movement control of the movable body using the at least three heads to movement control of the movable body using at least three heads including the different head whose correction information has been acquired instead of one of the at least three heads, before the measurement beam of one of the at least three heads moves off of the at least two of the plurality of first grating areas and the plurality of second grating areas including the another first grating area and the another second grating area.
