LIQUID IMMERSION MEMBER, EXPOSURE APPARATUS, EXPOSURE METHOD, DEVICE FABRICATING METHOD, PROGRAM, AND RECORDING MEDIUM |
摘要 |
A liquid immersion member forms a liquid immersion space on an object movable below an optical member so that a light path of exposure light emitted from an emission surface of the optical member is filled with liquid. The liquid immersion member includes a first member which is disposed in at least a portion of a periphery of the optical member, a second member which is movable relative to the first member and which includes a recovery port that recovers at least a portion of the liquid in the liquid immersion space, and a gas supply opening facing a gap between the first member and the second member, from which gas is supplied to the gap. |
