Abstract:
In an exposure apparatus that has an illumination optical system to illuminate a mask with an illumination light and a projection optical system to project a pattern image of the illuminated mask onto a substrate, first and second movable bodies, respectively holding the mask and the substrate, are moved based on measurement information of first and the second encoder systems so that, in an exposure operation of the substrate, scanning exposure in which the mask and the substrate are each moved relative to the illumination light is performed with a first direction within the predetermined plane serving as a scanning direction while compensating for a measurement error of the second encoder system that occurs due to at least one of tilt of the second head of the second encoder system and tilt in telecentricity of the second head.

Claim (Index 20):
The exposure method according to  claim 18 , wherein\n the first grating section has a pair of first scale members that are disposed on both sides of an illumination area of the mask, irradiated with the illumination light, in a second direction orthogonal to the first direction within the predetermined plane, and the plurality of first heads include at least two first heads at least one each of which is disposed on each of both sides of the illumination area in the second direction so that the pair of first scale members are each irradiated with the first measurement beam.
