A method and apparatus for heating a substrate is provided herein. In one embodiment, a substrate heater includes a vessel having an upper member including a top surface for supporting a substrate thereon; a liquid disposed within and partially filling the vessel; and a heat source for providing sufficient heat to the liquid to boil the liquid. Optionally, a pressure controller for regulating the pressure within the vessel may be provided. The substrate is heated by first placing the substrate on the support surface of the vessel of the substrate heater. The liquid contained in the vessel is then boiled. As the liquid is boiling, a uniform film of heated condensation is deposited on a bottom side of the support surface. The heated condensation heats the support surface which in turn, heats the substrate.
