Abstract:
In an exposure apparatus, on a substrate holder, a plurality of grating areas is arranged mutually apart in the X-axis direction, and a plurality of heads that irradiates a measurement beam with respect to the grating area and can move in the Y-axis direction is arranged outside of the substrate holder. A control system controls movement of the substrate holder in at least directions of three degrees of freedom within an XY plane, based on measurement information of at least three heads of the plurality of heads facing the grating area and measurement information of a measurement device that measures position information of the plurality of heads. The measurement beam of each of the plurality of heads, during the movement of substrate holder in the X-axis direction, moves off of one of the plurality of grating areas and switches to another adjacent grating area.

Claim (Index 151):
The exposure method according to  claim 145 , wherein\n the scale member has a plurality of grating sections arranged mutually separate in the second direction, the measurement system measures position information of the plurality of heads by the measurement device having a plurality of the second heads including at least two of the second heads whose position of the measurement beams is different in the second direction, and the at least two of the second heads irradiate the measurement beams at a spacing wider than a pair of adjacent grating sections of the plurality of grating sections in the second direction.
