Abstract:
An immersion type exposure apparatus comprises: an optical member from which an exposure beam is emitted; a first movable member that is movable while holding a substrate, in a predetermined region including a first region including a position facing the optical member and a second region different from the first region; a second movable member that is movable while holding the substrate independently from a first movable member, in a predetermined region including the first region and the second region; a first connection member that is releasably and alternately connected with the first movable member and the second movable member, and moves one movable member in the first region; a second connection member that is releasably and alternately connected with the first movable member and the second movable member, and moves the other movable member in the second region; and a third movable member that is provided on the first connection member and is movable to a position facing the optical member; and at least one of the first movable member, the second movable member, and the third movable member is moved to the position facing the optical member so that a beam path on the emitting side of the optical member is kept filled with a liquid.
