Patent ID: 8896807

Claim:
A liquid immersion lithography apparatus comprising: a projection system having a final optical element via which a substrate is exposed to an exposure beam through an immersion liquid located between the final optical element and the substrate; and a nozzle member having: an undersurface that surrounds a path of the exposure beam; a first opening disposed on one side of the final optical element and from which the immersion liquid is supplied; a second opening disposed on a second side of the final optical element and from which the immersion liquid is collected; and a liquid recovery portion disposed such that the liquid recovery portion surrounds the path of the exposure beam and from which the immersion liquid is collected, wherein the nozzle member is spaced from the final optical element, the first and second openings of the nozzle member are located higher than the undersurface of the nozzle member, during the exposure, an upper surface of the substrate faces the liquid recovery portion, during the exposure, the immersion liquid is supplied from the first opening while the immersion liquid supplied from the first opening is recovered from the second opening and the liquid recovery portion, and the liquid recovered through the second opening is not collected through the liquid recovery portion.
