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 25):
The exposure method according to  claim 18 , wherein\n in each of the exposure operation and a detection operation of a mark of the substrate or a mark of the second movable body by a second detection system, the positional information of the second movable body is measured by the second encoder system, the second detection system being disposed spaced from the projection optical system and measuring the mark.
