More Information
Summary:A fluid handling system for a lithographic apparatus, the fluid handling system configured to confine immersion liquid to a liquid confinement space between a part of a projection system and a surface of a substrate in the lithographic apparatus wherein a radiation beam projected from the projection system can irradiate the surface of the substrate by passing through the immersion liquid, the fluid handling system including: a liquid extraction member, having an inlet side and an outlet side, that is arranged to extract the immersion liquid from the liquid confinement space by a fluid flow from the inlet side to the outlet side; and a further liquid supply to the outlet side of the liquid extraction member arranged so that the outlet side receives liquid from a different source than the liquid confinement space.
