Abstract:
A liquid immersion exposure apparatus and method expose a substrate with illumination light via liquid. A projection optical system has plural optical elements that include a lens contacting the liquid and a barrel supporting the optical elements, the lens provided on a front end part of the projection optical system and exposed from the barrel. A liquid immersion member around the lens forms a liquid immersion area between the lens and part of the substrate. A drive device having a magnetic floating type of motor moves a substrate stage below the projection optical system. The liquid immersion member has a supply port to supply the liquid below the projection optical system and a recovery port to recover the liquid. The supply port is outside the projection area, the recovery port surrounds the projection area and the supply port, and each of the supply and recovery ports faces the substrate stage.

Claim (Index 20):
A manufacturing method of a liquid immersion exposure apparatus that exposes a substrate with illumination light via a liquid, the method comprising:\n providing a projection optical system having a plurality of optical elements that include a lens coming into contact with the liquid and a barrel that supports the plurality of optical elements, the lens being provided on a front end part of the projection optical system such that the lens is exposed from the barrel; providing a liquid immersion member provided around the lens and configured to form a liquid immersion area between the lens and part of the substrate by the liquid so as to include a projection area to be irradiated with the illumination light via the projection optical system and the liquid; providing a substrate stage arranged below the projection optical system and the liquid immersion member and configured to hold the substrate; providing a drive device having a motor of a magnetic floating type configured to move the substrate stage; and providing a controller configured to control the drive device such that the substrate is moved relative to the liquid immersion area maintained between the lens and the part of the substrate, wherein the liquid immersion member has a supply port configured to supply the liquid below the projection optical system and a recovery port configured to recover the liquid of the liquid immersion area, the supply port being arranged outside the projection area, the recovery port being arranged so as to surround the projection area and the supply port, and each of the supply port and the recovery port being provided so as to face the substrate stage arranged below the projection optical system.
