    摘要: A process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after depositing a layer of material over a substrate disposed in the chamber. In one embodiment the process comprises transferring the substrate out of the chamber; flowing a first gas into the substrate processing chamber and forming a plasma within the chamber from the first gas in order to heat the chamber; and thereafter, extinguishing the plasma, flowing an etchant gas into a remote plasma source, forming reactive species from the etchant gas and transporting the reactive species into the substrate processing chamber to etch the unwanted deposition build-up.
