衬底保持器、光刻设备及制造器件的方法
摘要：
一种用于光刻设备中并且配置成支撑衬底的衬底保持器(WT)，该衬底保持器包括：主体(21)，具有主体表面；多个突节(20)，从主体表面突出以支撑衬底使得衬底与主体表面分隔开；和液体控制结构(200)，设置在主体表面的周边区域(22a)中并且配置成使得液体优先朝向主体表面的周边流动。
摘要（英）：

A substrate holder (WT) for use in a lithographic apparatus and configured to support a substrate (W), the substrate holder comprising: • a main body (21) having a main body surface (22); • a plurality of burls (20) projecting from the main body surface to support the substrate spaced apart from the main body surface; and • a liquid control structure (200) provided in a peripheral region (22a) of the main body surface and configured to cause liquid to preferentially flow toward the periphery of the main body surface.
