    Abstract: A wafer chuck assembly includes a puck, a shaft and a base. An insulating material defines a top surface of the puck, a heater element is embedded within the insulating material, and a conductive plate lies beneath the insulating material. The shaft includes a housing coupled with the plate, and electrical connectors for the heater elements and the electrodes. A conductive base housing couples with the shaft housing, and the connectors pass through a terminal block within the base housing. A method of plasma processing includes loading a workpiece onto a chuck having an insulating top surface, providing a DC voltage differential across two electrodes within the top surface, heating the chuck by passing current through heater elements, providing process gases in a chamber surrounding the chuck, and providing an RF voltage between a conductive plate beneath the chuck, and one or more walls of the chamber.

    Abstract: Methods of removing contamination from the surface of a substrate are described. The etch selectively removes alkali metals and alkali earth metals from substrates. The alkali metals may include sodium, lithium, rubidium or potassium and the alkali earth metals may include calcium. For example, the etch may remove contaminants by generating and then desorbing volatile chemical species from the substrate. A hydrogen-and-oxygen-containing precursor or combination of precursors is flowed into a remote plasma to form plasma effluents. The plasma effluents are then flowed into the substrate processing region to react with the substrate and remove an alkali metal and/or an alkali earth metal from the surface of the substrate. No local plasma excites the plasma effluents in embodiments.
