Abstract:
A liquid crystal exposure apparatus that moves a substrate supported in a noncontact manner by a noncontact holder to a projection optical system, and performs scanning exposure to the substrate equipped with: holding pads that hold a part of the substrate located at a first position above the noncontact holder; adsorption pads that hold another part of the substrate; a first drive section moves the holding pads from below the substrate direction intersecting a vertical direction, where the substrate is located at the first position held by the adsorption pads; and a second drive section that moves the adsorption pads holding the substrate, to a second position where the substrate is supported in a noncontact manner by the noncontact holder, wherein the scanning exposure, the second drive section moves the adsorption pads holding the substrate supported in a noncontact manner by the noncontact holder to the projection optical system.
