Abstract:
A lithographic projection apparatus that is arranged to project a pattern from a patterning device onto a substrate using a projection system has a liquid supply system arranged to supply a liquid to a space between the projection system and the substrate. The apparatus also includes a liquid collecting system that includes a liquid collection member having a permeable member through which a liquid is collected from a surface of an object opposite to the liquid collection member, wherein the permeable member has a plurality of passages that generate a capillary force.
