Abstract: A liquid crystal exposure apparatus has a measurement system having scales arranged apart from each other in the X-axis direction provided at a substrate stage holding a substrate and heads each irradiating the scales with a measurement beam; and a measurement device that measures positions of head units in the Y-axis direction. The measurement system measures a position of the substrate holder in directions of three degrees of freedom within a plane, based on measurement information of at least three heads. Each of 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 using the head moving to irradiate another scale is acquired, based on measurements of at least three heads.

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.
