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 2):
The exposure apparatus according to  claim 1 , wherein\n the second grating section has four second scale members in each of which the reflective grating is formed, and the controller compensates for the measurement error of the second encoder system that occurs due to displacement of the second grating section.
