Abstract:
1. A substrate chuck within a vacuum chamber of an ion implantation system for supporting a substrate and controlling a heat transfer associated therewith, the substrate chuck comprising: a support mechanism comprising a clamping surface to hold a substrate during ion implantation and to facilitate movement of the wafer in at least one dimension; a cooling mechanism coupled to the support mechanism; a thermos layer substantially surrounding the substrate chuck outside of the clamping surface, the thermos layer comprising: wherein the thermos layer creates a vacuum barrier between the support mechanism and outside of the support mechanism thereby preventing condensation on and heat transfer to the walls of the support mechanism, wherein the outer casing of the thermos layer further comprises an orifice, and the vacuum gap comprises a first vacuum generated by a second vacuum within the vacuum chamber via fluid connection therebetween via the orifice.
