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 80):
An exposure method irradiating an object with an illumination light via an optical system, comprising:\n measuring position information of a movable body that holds the object at least in directions of three degrees of freedom within a predetermined plane orthogonal to an optical axis of the optical system by a measurement system having a grating member with a plurality of first grating areas arranged mutually apart in the first direction within the predetermined plane and a plurality of second grating areas arranged mutually apart in the first direction at positions different from the plurality of first grating areas in the second direction, a plurality of heads irradiating the grating member with a measurement beam from each of the heads that can move in the second direction, and a measurement device that measures position information of the plurality of heads in the second direction, in which one of the grating member and the plurality of heads is provided at the movable body, along with the other of the grating member and the plurality of heads being provided facing the movable body, based on measurement information of at least three heads of the plurality of heads irradiating at least two of the plurality of first grating areas and the plurality of second grating areas with the measurement beam and measurement information of the measurement device; and moving the movable body based on position information measured by the measurement system, wherein the measurement beam of each of the plurality of heads moves off of one grating area of the plurality of first grating areas or the plurality of second grating areas, and moves to irradiate one grating area of another first grating area or another second grating area adjacent to the one grating area of the first grating area or the second grating area while the movable body is being moved in the first direction, and correction information to control movement of the movable body using a head different from the at least three heads of the plurality of heads whose measurement beams have moved off of one of the first grating area and the second grating area and move to irradiate the another of the first grating area and the second grating area is acquired, based on measurement information of the at least three heads or position information of the movable body measured using the at least three heads.
