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 139):
The exposure method according to  claim 138 , wherein\n the plurality of heads includes at least one head whose non-measurement section at least partly overlaps with the non-measurement section of at least one of the at least four heads, and in measurement of position information of the movable body, of at least five heads including the at least four heads and the at least one head, measurement information is used of at least three heads irradiating at least one of the plurality of grating areas with the measurement beam.
