Beschreibung
Zusammenfassung:	A movable body apparatus has: a substrate holder holding a substrate and can move in the X and Y-axes directions; a Y coarse movement stage movable in the Y-axis direction; a first measurement system acquiring position information on the substrate holder by heads on the substrate holder and a scale on the Y coarse movement stage; a second measurement system acquiring position information on the Y coarse movement stage by heads on the Y coarse movement stage and a scale; and a control system controlling the position of the substrate holder based on position information acquired by the first and second measurement systems. The first measurement system irradiates a measurement beam while moving the heads in the X-axis direction with respect to the scale, and the second measurement system irradiates a measurement beam while moving the heads in the Y-axis direction with respect to the scale.
