摘要:
An immersion lithography apparatus includes (i) an optical assembly including an optical element, and configured to project a beam onto a substrate through an immersion liquid; (ii) a containment member that surrounds a path of the beam; and (iii) a stage on which the substrate is held, the substrate on the stage being moved below and spaced from a bottom surface of the containment member. The containment member includes: (1) a nozzle outlet via which water as the immersion liquid is released, (2) a recovery channel via which the immersion liquid is recovered from a gap between the containment member and the substrate and/or the stage, and (3) a fluid channel via which water is released to the gap between the containment member and the substrate and/or the stage, the fluid channel being provided radially inward of the recovery channel.
