Abstract:
1. An exposure apparatus which exposes a substrate by forming a liquid immersion area on a part of the substrate and projecting an image of a pattern onto the substrate through a liquid in the liquid immersion area, the exposure apparatus comprising: a projection optical system which projects the image of the pattern onto the substrate; a substrate stage on which the substrate is held, the substrate stage being movable below the projection optical system; a liquid supply system having a supply inlet, which supplies the liquid onto the substrate to form the liquid immersion area; a first liquid recovery system having a recovery port, which recovers the liquid from above a surface of the substrate; and a second liquid recovery system which has a recovery port provided on the substrate stage and which recovers the liquid from a space under the projection optical system after completion of the exposure for the substrate.
