A system and method for removing both carbon-based contaminants and oxygen-based contaminants from a semiconductor substrate within a single process chamber is disclosed. The invention may comprise utilization of remote plasma units and multiple gas sources to perform the process within the single process chamber. 1. An apparatus for processing a semiconductor substrate comprising:a reaction chamber;a susceptor configured to hold a substrate;a first gas source for providing a first gas;a second gas source for providing a second gas;a first remote plasma unit configured to receive the first gas and produce a first radical gas;a gas distribution device configured to flow the first radical gas and the second gas onto the substrate; anda transport path connecting the remote plasma unit to the gas distribution device, wherein the first radical gas passes through the gas distribution device onto the substrate;{'sub': 2', '3', '2', '3', '2', '3', '2', '2', '3', '2', '2', '3, 'wherein the gas distribution device, the reaction chamber, the transport path, and the susceptor are coated with at least one of: anodized aluminum oxide (AlO); atomic layer deposition (ALD)-formed aluminum oxide; plasma sprayed AlO; bare aluminum parts with native aluminum oxide; yttrium oxide (YO); yttrium oxide stabilized zirconium oxide (YSZ); zirconium oxide (ZrO); lanthanum zirconium oxide (LZO); yttrium aluminum garnet (YAG); yttrium oxyfluoride (YOF); aluminum oxide (AlO); zirconium oxide (ZrO); yttrium oxide (YO); or yttrium oxide stabilized zirconium oxide (YSZ).'}2. The apparatus of claim 1 , wherein the first gas comprises at least one of: NF claim 1 , CF claim 1 , CF claim 1 , CF claim 1 , CF claim 1 , COF claim 1 , SF claim 1 , or WF.3. The apparatus of claim 1 , wherein the second gas comprises at least one of: H claim 1 , NH claim 1 , HO claim 1 , O claim 1 , or O.4. The apparatus of claim 1 , further comprising:a third gas source for providing a third gas; anda fourth gas source for ...
