Abstract: A fluid handling structure for a lithographic apparatus configured to contain immersion fluid to a region, the fluid handling structure having, at a boundary of a space: at least one gas knife opening in a radially outward direction of the space; and at least one gas supply opening in the radially outward direction of the at least gas knife opening relative to the space. The gas knife opening and the gas supply opening both provide substantially pure CO2 gas so as to provide a substantially pure CO2 gas environment adjacent to, and radially outward of, the space.

Abstract: A substrate table configured to support a substrate for exposure in an immersion lithographic apparatus, the substrate table including: a support body having a support surface configured to support the substrate; and a cover ring fixed relative to the support body and configured to surround, in plan view, the substrate supported on the support surface, wherein the cover ring has an upper surface, wherein at least a portion of the upper surface is configured so as to alter the stability of a meniscus of immersion liquid when moving along the upper surface towards the substrate.
