Abstract:
An exposure apparatus includes a sensor for detecting light arriving from a projection optical system via a liquid provided on an image plane side of the projection optical system. The sensor includes a light transmissive member provided on a stage and a light receiving element for receiving light arriving from the projection optical system via the light transmissive member. The light transmissive member includes a first surface and a second surface. The first surface is arranged on the stage, comes into contact with the liquid, and is a surface on which the light arriving from the projection optical system is incident via the liquid. At least one of the first and second surfaces diffuses or diffracts the light having arrived from the projection optical system. The light receiving element receives the light that has been diffused or diffracted.

Claim (Index 1):
An exposure apparatus for exposing a substrate to light via liquid, the exposure apparatus comprising:\n a stage for holding the substrate; a projection optical system for projecting a pattern image onto the substrate held on the stage via the liquid provided on an image plane side of the projection optical system; and a sensor for detecting light arriving from the projection optical system via the liquid provided on the image plane side of the projection optical system, wherein the sensor comprises a light transmissive member provided on the stage and a light receiving element for receiving light arriving from the projection optical system via the light transmissive member, the light transmissive member includes a first surface and a second surface, the first surface being arranged on the stage so as to come into contact with the liquid and being a surface on which the light arriving from the projection optical system is incident via the liquid, at least one of the first surface and the second surface being configured to diffuse or diffract the light having arrived from the projection optical system, the light transmissive member being configured so that light from the projection optical system arrives at the second surface via the liquid and the first surface without passing through a gas portion, and the light receiving element is arranged to receive light diffused or diffracted by at least one of the first surface and the second surface of the light transmissive member.
