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 30):
The exposure method according to  claim 29 , wherein\n before the switching, the positional information of the second stage is measured by three of the heads that face three of the four scale members, respectively, one head of the three heads is switched to the another head that is different from the three heads, and after the switching, the positional information of the second stage is measured by three heads that include two remaining heads and the another head, the two remaining heads excluding the one head of the three heads used before the switching.
