    Abstract: Substrate tables for lithography and methods of handling a substrate. In one arrangement, a substrate table includes 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 includes 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.
