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 18):
An exposure method of illuminating a mask with an illumination light and exposing a substrate with the illumination light via a projection optical system, the method comprising:\n moving a first movable body that holds the mask in a recessed portion, on a first base member disposed above the projection optical system and having an opening through which the illumination light passes; in a first encoder system in which one of a first grating section and first heads is provided at the first movable body, measuring positional information of the first movable body, with a plurality of the first heads that each irradiate a reflective grating of the first grating section with a first measurement beam; moving a plurality of second movable bodies that each are configured to hold the substrate, on a second base member disposed below the projection optical system; measuring positional information of the second movable bodies, with a second encoder system that has a plurality of second heads, the plurality of second heads each irradiating a second grating section having a reflective grating with a second measurement beam, and the second grating section being disposed substantially parallel to a predetermined plane that is orthogonal to an optical axis of the projection optical system; moving the first and the second movable bodies based on measurement information of the 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; and compensating for a measurement error of the second encoder system that occurs due to at least one of tilt of the second head and tilt in telecentricity of the second head.
