    摘要: A fluid handling structure for a lithographic apparatus, the fluid handling structure having, at a boundary from a space configured to contain immersion fluid to a region external to the fluid handling structure: a meniscus pinning feature to resist passage of immersion fluid in a radially outward direction from the space; a plurality of gas supply openings in a linear array at least partly surrounding and radially outward of the meniscus pinning feature; and a gas recovery opening radially outward of the plurality of gas supply openings in a linear array.
