Abstract:
An exposure apparatus includes (i) a projection optical system, (ii) a substrate stage having a substrate holder on which a substrate is held, which is movable while holding the substrate with the substrate holder, and (iii) a reference member having a first reference and a second reference for performing an alignment process, the reference member being provided on the substrate stage. At least part of an upper surface of the reference member includes a liquid repellent material. The substrate is aligned based on information obtained from the alignment process. The substrate is exposed through liquid in a liquid immersion area formed locally on an upper surface of the substrate.

Claim (Index 3):
The exposure apparatus according to  claim 1 , wherein\n the substrate stage has a recess in which the substrate is held, and the substrate stage has an upper surface which is substantially flush with an upper surface of the reference member, and the substrate is held in the recess such that the upper surface of the substrate is substantially flush with the upper surface of the substrate stage.
