Abstract:
A substrate holder (WT) for use in a lithographic apparatus and configured to support a substrate, the substrate holder comprising: a main body ( 20 ) having a main body surface; and a plurality of burls ( 21 ) projecting from the main body surface; wherein each burl has a distal end configured to engage with the substrate; the distal ends of the burls substantially conform to a support plane whereby a substrate can be supported in a substantially flat state on the burls; and a flow control feature ( 22, 22 c,  22 d ) configured to form a gas cushion adjacent the periphery of the substrate holder when a substrate is being lowered onto the substrate holder.

Claim (Index 1):
A substrate holder for use in a lithographic apparatus and configured to support a substrate, the substrate holder comprising:\n a main body having a main body surface; a plurality of burls projecting from the main body surface; wherein\n each burl has a distal end configured to engage with the substrate; \n the distal ends of the burls substantially conform to a support plane whereby a substrate can be supported in a substantially flat state on the burls; and \n a flow control feature configured to form a gas cushion adjacent the periphery of the substrate holder when a substrate is being lowered onto the substrate holder, wherein the flow control feature comprises a raised area adjacent a periphery of the substrate holder and wherein the raised area has a distal surface that is inclined to the support plane.
