Abstract:
An exposure apparatus that scans and exposes each of a plurality of areas on a glass substrate, by irradiating the substrate with an illumination light via a projection optical system and relatively driving the substrate with respect to the illumination light, is equipped with: a substrate holder that levitates and supports a first area of the substrate; a substrate carrier that holds the glass substrate levitated and supported by the substrate holder; an X coarse movement stage that drives the substrate holder; an X voice coil motor that drives the substrate carrier; and a controller that controls the X coarse movement stage and the X voice coil motor so that the substrate holder and the substrate carrier are driven, respectively, in scanning exposure. Accordingly, an exposure apparatus with improved position controllability of an object can be provided.
