Abstract:
An immersion lithographic apparatus having a fluid handling structure, the fluid handling structure configured to confine immersion fluid to a region and including: a meniscus controlling feature having an extractor exit on a surface of the fluid handling structure; and a gas knife system outwards of the extractor exit and including passages each having an exit, the passages having a plurality of first passages having a plurality of corresponding first exits on the surface, and a plurality of second passages having a plurality of corresponding second exits outwards of the first exits on the surface, wherein the surface faces and is substantially parallel to a top surface of a substrate during exposure, and the first exits and the second exits are arranged at a greater distance from the substrate than the extractor exit.

Claim (Index 1):
An immersion lithographic apparatus comprising a fluid handling structure, the fluid handling structure configured to confine immersion fluid to a region and comprising:\n a meniscus controlling feature having an extractor exit on a surface of the fluid handling structure; and a gas knife system outwards, relative to a center of the fluid handling structure, of the extractor exit and comprising passages each having an exit, the passages comprising a plurality of first passages having a plurality of corresponding first exits on the surface, and a plurality of second passages having a plurality of corresponding second exits, the second exits located outward, relative to the center of the fluid handling structure, of the first exits on the surface, wherein the surface faces and is substantially parallel to a top surface of a substrate during exposure, and the first exits and the second exits are arranged at a greater distance from the substrate than the extractor exit.
