Patent ID: 7105836

Claim:
A short stroke stage for use in a lithography system, comprising: a radiative coupler having a base plate coupled to a first plurality of extensions, the radiative coupler comprised of a conductive material; a rigid structure having a plurality of struts with tips, the rigid structure comprised of a substantially zero coefficient of thermal expansion material; an electrostatic chuck having a heat spreader plate coupled to a second plurality of extensions that mechanically couple the electrostatic chuck to the radiative coupler base plate, the heat spreader plate having a plurality of holes to allow the tips of the rigid structure struts to pass there through so as to support the substrate; and flexures that mechanically couple the radiative coupler to the rigid structure, wherein during operation, the electrostatic chuck secures a substrate, such as a wafer or a reticle, within the lithography system, and the electrostatic chuck and radiative coupler are thermally coupled so as to conduct heat away from the substrate.
