Abstract:
An exposure apparatus exposes a substrate with illumination light via a projection optical system, and includes a stage disposed below the projection optical system and holds the substrate; an encoder system in which one of a grating section and a head is provided at the stage and the other of the grating section and the head is provided at a frame member disposed above the stage, on a lower end side of the projection optical system, and which irradiates the grating section with a measurement beam via the head and measures positional information of the stage with a plurality of the heads that face the grating section; and a controller coupled to the encoder system, that controls a drive system based on positional information measured with the encoder system while compensating for measurement error of the encoder system related to measurement direction of the positional information by the heads.

Claim (Index 9):
The exposure apparatus according to  claim 2 , wherein\n the third stage has at least one measurement member that detects the illumination light via the projection optical system and the liquid of the liquid immersion area, and at least one of illuminance measurement, aerial image measurement and wavefront aberration measurement is performed by the at least one measurement member.
