Stage apparatus, exposure apparatus, method of manufacturing flat panel display, and device manufacturing method

Abstract

A stage apparatus includes a movable body having a first support surface for supporting an object, a support portion that is elastically deformable, has a predetermined thickness, and supports the movable body, a support device having a second support surface that supports the support portion, and a drive unit configured to move the movable body so that an angle between the first support surface and the second support surface is changed, wherein the support portion elastically deforms so that the predetermined thickness at a first side where an interval between the first support surface and the second support surface is narrow becomes small and the predetermined thickness at a second side where the interval between the first support surface and the second support surface is wide becomes large in accordance with a change in the angle caused by the drive unit to support the movable body.
