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 17):
The liquid immersion exposure method according to  claim 11 , wherein\n part of the liquid immersion member coming into contact with the liquid of the liquid immersion area is moved regarding a direction which is perpendicular to an optical axis of the projection optical system.
