Abstract:
A liquid immersion exposure apparatus is disclosed. It includes a projection system having a final element and a liquid immersion member that in turn includes a first member, which surrounds the final element and has a liquid supply port and a liquid suction port, and a second member, which is movable with respect to the first member and has a lower part under which a portion of a liquid immersion space is formed. During exposure of a plurality of shot regions of a substrate, the immersion space covers a portion of a surface of the substrate, and the first shot region is exposed while moving the substrate in a first scanning direction. After the exposure of the first shot region, the second shot region is exposed while moving the substrate in a second scanning direction.

Claim (Index 1):
A liquid immersion exposure apparatus comprising:\n a projection system having a final element; a liquid immersion member that forms a liquid immersion space under the final element, and a stage having a holding portion on which a substrate is held, the stage being movable below the final element, wherein: the liquid immersion member includes a first member that surrounds the final element and that has a liquid supply port and a first liquid suction port; and the liquid immersion member includes a second member that is movable with respect to the first member, the second member has a lower part under which a portion of the liquid immersion space is formed, the second member has a second liquid suction port provided in the lower part, the second member is moved in a moving direction substantially perpendicular to an optical axis of the final element such that a relative speed between the second member and the stage becomes lower than a relative speed between the first member and the stage, and a recovery operation, which is performed using the second liquid suction portion, is controlled based on a movement condition of the stage.
