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 34):
The exposure method according to  claim 33 , wherein\n the substrate is held in a recessed portion of an upper surface of the second stage so that a surface of the substrate and the upper surface are substantially flush, the second stage is moved below the other of the grating section and the heads provided at the frame member so that the other of the grating section and the heads is disposed on an outer side of the nozzle member with respect to the projection optical system, and at least a part of the liquid immersion area that moves off from the substrate held in the recessed portion is maintained with the upper surface.
