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 10):
The exposure apparatus according to  claim 9 , further comprising a first detecting system arranged apart from the projection optical system, which detects an alignment mark on the substrate held by the substrate stage not through the liquid and which detects the first reference of the reference member not through the liquid.
