Claim Text:
1. An exposure apparatus that exposes a substrate by exposure light via liquid between an emitting surface of an optical member and the substrate, the exposure apparatus comprising: a liquid immersion member configured to form a liquid immersion space on an object and comprising a first member and a second member, the first member being disposed at least at a portion surrounding the optical member, the second member being disposed at least at a portion surrounding an optical path of the exposure light below the first member, the second member being movable with respect to the first member and comprising a second upper surface and a second lower surface, the second upper surface being opposite to a first lower surface of the first member via a gap, the second lower surface being capable of being opposite to the object, the object being movable below the optical member; and a vibration isolator configured to suppress a vibration of the first member, wherein the object comprises the substrate, in a state where the liquid immersion space is formed, the substrate moves in a second pathway after moving in a first pathway within a plane substantially perpendicular to an optical axis of the optical member, the movement of the substrate in the first pathway comprises a movement in a second direction substantially parallel with a second axis in the plane, the movement of the substrate in the second pathway comprises a movement in a third direction substantially parallel with a third axis orthogonal to the second axis in the plane, and the second member moves in the third direction in at least a part of a period while the substrate is moving in the second pathway, and the exposure light is radiated to a shot region of the substrate via liquid of the liquid immersion space while the substrate is moving in the first pathway, and the exposure light is not radiated while the substrate is moving in the second pathway.
