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 122):
An exposure method irradiating an object with an illumination light via an optical system, comprising:\n measuring position information of a movable body in at least directions of three degrees of freedom within a predetermined plane orthogonal to an optical axis of the optical system by a measurement system in which one of a grating member with a plurality of grating areas arranged apart from the plurality of first grating areas in a second direction orthogonal to the first direction within the predetermined plane and apart from one another in the first direction, and a plurality of heads each irradiating the grating member with a measurement beam that can move in the second direction orthogonal to the first direction within the predetermined plane is provided at the movable body, and the other of the grating member and the plurality of heads is provided facing the movable body, and by the measurement system having a measurement device that measures position information of the plurality of heads in the second direction, position information of the movable body is measured based on measurement information of at least three heads of the plurality of heads irradiating at least one of the plurality of grating areas with the measurement beams and measurement information of the measurement device; and moving the movable body based on position information measured by the measurement system; wherein with each of the plurality of heads, the measurement beam moves off one of the plurality of grating areas, and moves to irradiate another grating area adjacent to the one grating area while the movable body is moving in the first direction.
