Abstract:
A liquid immersion exposure apparatus includes a liquid-immersion-area-forming-member having an opening through which an exposure light is projected, the-liquid-immersion-area-forming-member having a first liquid supply inlet facing downward, a second liquid supply inlet provided opposite to an outer surface of the final optical element, and a first removal outlet facing downward. A liquid immersion area is formed on a portion of an upper surface of a substrate while performing a liquid supply via the first liquid supply inlet to a gap between the liquid-immersion-area-forming-member and the upper surface of the substrate, a liquid supply via the second liquid supply inlet to a gap between the liquid-immersion-area-forming-member and a final optical element of a projection system and a liquid removal via the first removal outlet from the gap between the liquid-immersion-area-forming-member and the upper surface of the substrate.
