Abstract:
1. A substrate heat exchange pedestal comprising: (a) a support structure comprising a metal body having a contact surface comprising a coating of a diamond-like carbon material comprising a composition of from about 50 atom % to about 90 atom % carbon, from about 5 atom % to about 10 atom % hydrogen, from about 10 atom % to about 20 atom % silicon, and from about 5 atom % to about 10 atom % oxygen, to provide a coefficient of friction of less than about 0.3, an average surface roughness of less than about 0.4 micrometers, and a microhardness of at least about 8 GPa; and (b) an adhesion layer below the diamond-like carbon material, the adhesion layer comprising metal; and (c) a heat exchanger in the support structure, the heat exchanger capable of heating a substrate.
