    摘要: A substrate holder for use in a lithographic apparatus. The substrate holder comprises a main body (400) and a plurality of burls provided on the main body and having end surfaces to support a substrate. The burls each comprise a lower portion (406a) protruding from the main body and an upper portion (406b) above the lower portion. The lower portions are a different material than the upper portions, the upper portions comprise diamond-like carbon, and the upper portions are separated from each other.

    摘要: The disclosure relates to substrate tables for lithography and methods of handling a substrate. In one arrangement, a substrate table comprises one or more membranes. An actuation system deforms each membrane to change a height of a portion of the membrane. In another arrangement, a substrate table comprises one or more membranes and a clamping system for clamping a substrate to the substrate table, wherein the clamping deforms each membrane by pressing the substrate against the membrane.
