Abstract
A method including: generating a first force to attract a substrate holder to a support surface, the holder including a body having opposing first and second body surfaces, first burls at the first body surface, wherein each first burl has a distal end to support a substrate, and second burls at the second body surface to support the substrate holder on the support surface through contact with distal ends of the second burls; generating a second force to attract the substrate to the substrate holder; and controlling the first force and/or second force in a release step to deform the body between the second burls such as to create a gap between the distal ends of a first subset of the plurality of first burls and the substrate and such that the substrate is supported on distal ends of a second subset of the plurality of first burls.
