    Abstract: 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; and a plurality of gas supply openings in a linear array at least partly surrounding and radially outward of the one or more meniscus pinning features, wherein the plurality of gas supply openings in a linear array are of a similar or the same size.

    Abstract translation: 一种用于光刻设备的流体处理结构,所述流体处理结构在从被配置为将浸没流体包含在流体处理结构外部的区域的空间的边界处具有:弯液面锁定特征,以阻止浸没流体在径向向外 方向从空间; 以及线性阵列中的至少部分地围绕并径向向外的一个或多个弯液面钉扎特征的多个气体供应开口,其中线性阵列中的多个气体供应开口具有相似或相同的尺寸。
