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 102):
The exposure apparatus according to  claim 1 , wherein\n in the measurement device, one of a scale member and a second head is provided at the plurality of heads and the other of the scale member and the second head is provided facing the plurality of heads, and the measurement device measures position information of the plurality of heads in the second direction by irradiating the scale member with a measurement beam via the second head.
