Abstract:
A liquid immersion member is used in a liquid immersion exposure apparatus, and forms a liquid immersion space above an object which is movable below the optical member. The liquid immersion member includes a first member that is disposed at at least a portion of surrounding of the optical member, and a second member that is disposed at at least a portion of surrounding of an optical path of the exposure light and is relatively movable with respect to the first member. The second member includes a second upper surface that is opposite to a first lower surface of the first member via a gap, a second lower surface that is capable of being opposite to the object, and a fluid recovery part that is disposed at at least a portion of surrounding of the second lower surface.

Claim (Index 11):
A liquid immersion exposure apparatus comprising:\n a projection system having a final element; and a liquid immersion member that forms a liquid immersion space under the final element, wherein: the liquid immersion member includes a first member that surrounds the final element and that has a liquid supply port, a first recovery part and an outer surface; the liquid immersion member includes a second member under which a portion of the liquid immersion space is formed, the second member being movable with respect to the first member in a moving direction substantially perpendicular to an optical axis of the final element, the second member having a second recovery part and an inner surface opposite to the outer surface of the first member, and a distance between the inner surface and the outer surface being changed by moving the second member in the moving direction; during exposure of a plurality shot regions of a substrate including first and second shot regions, the immersion space covers a portion of a surface of the substrate, while recovering liquid via the second recovery part from a gap between the second member and the substrate; 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 substantially opposite to the first scanning direction; during a stepping period after finishing the exposure of the first shot region but before starting the exposure of the second shot region, the substrate is moved in a stepping direction containing a component crossing the first scanning direction; during the stepping period, the second member is moved in the moving direction containing the component crossing the first scanning direction such that a relative speed between the second member and the substrate becomes lower than a relative speed between the first member and the substrate; and the second member starts moving in the moving direction before the exposure of the first shot region is finished.
