Claim 9:
10. A substrate oxidation assembly comprising:
a chamber body defining a processing volume;
a substrate support disposed in the processing volume and having an axis through a center of the substrate support, the substrate support comprising a resistive heating element having a circular shape;
a plasma source coupled to the processing volume;
a gas distributor coupled to the chamber body and coaxial with the axis of the substrate support;
a steam source fluidly coupled to the processing volume, comprising a catalytic steam generator, and configured to distribute steam symmetrically about the axis of the substrate support; and
a substrate heater configured to heat to between 700° C. and 1100° C., wherein the substrate heater includes one or more heating elements in physical contact with an edge of the substrate support.
