Abstract:
An exposure apparatus exposes a substrate with illumination light via a projection optical system and liquid, and includes a controller that controls movement of first and second movable members each of which can hold a substrate. The controller executes a relative movement between the first and second movable members such that, while one of the movable members is arranged opposed to the projection optical system, the other of the movable members comes close to the one of the movable members, and so as to move the close first and second movable members relative to the projection optical system such that the other of the movable members is arranged opposed to the projection optical system in place of the one of the movable members while substantially maintaining a liquid immersion region under the projection optical system.
