Abstract: Methods and apparatus for use of a fill on demand ampoule are disclosed. The fill on demand ampoule may refill an ampoule with precursor concurrent with the performance of other deposition processes. The fill on demand may keep the level of precursor within the ampoule at a relatively constant level. The level may be calculated to result in an optimum head volume. The fill on demand may also keep the precursor at a temperature near that of an optimum precursor temperature. The fill on demand may occur during parts of the deposition process where the agitation of the precursor due to the filling of the ampoule with the precursor minimally effects the substrate deposition. Substrate throughput may be increased through the use of fill on demand.

Abstract: Certain embodiments herein relate to an apparatus used for remote plasma processing. In various embodiments, the apparatus includes a reaction chamber that is conditioned by forming a low recombination material coating on interior chamber surfaces. The low recombination material helps minimize the degree of radical recombination that occurs when the reaction chamber is used to process substrates. During processing on substrates, the low recombination material may become covered by relatively higher recombination material (e.g., as a byproduct of the substrate processing), which results in a decrease in the amount of radicals available to process the substrate over time. The low recombination material coating may be reconditioned through exposure to an oxidizing plasma, which acts to reform the low recombination material coating. The reconditioning process may occur periodically as additional processing occurs on substrates.
