    摘要: The invention includes atomic layer deposition methods of depositing an oxide on a substrate. In one implementation, a substrate is positioned within a deposition chamber. A first species is chemisorbed onto the substrate to form a first species monolayer within the deposition chamber from a gaseous precursor. The chemisorbed first species is contacted with remote plasma oxygen derived at least in part from at least one of O2 and O3 and with remote plasma nitrogen effective to react with the first species to form a monolayer comprising an oxide of a component of the first species monolayer. The chemisorbing and the contacting with remote plasma oxygen and with remote plasma nitrogen are successively repeated effective to form porous oxide on the substrate. Other aspects and implementations are contemplated.

    摘要: A method of enhanced atomic layer deposition is described. In an embodiment, the enhancement is the use of plasma. Plasma begins prior to flowing a second precursor into the chamber. The second precursor reacts with a prior precursor to deposit a layer on the substrate. In an embodiment, the layer includes at least one element from each of the first and second precursors. In an embodiment, the layer is TaN. In an embodiment, the precursors are TaF5 and NH3. In an embodiment, the plasma begins during the purge gas flow between the pulse of first precursor and the pulse of second precursor. In an embodiment, the enhancement is thermal energy. In an embodiment, the thermal energy is greater than generally accepted for ALD (>300 degrees Celsius). The enhancement assists the reaction of the precursors to deposit a layer on a substrate.

    摘要: In one embodiment, the system includes a gas supply assembly having a first gas source, a first gas conduit coupled to the first gas source, a first valve assembly, a reaction chamber, and a gas distributor carried by the reaction chamber. The first valve assembly includes first and second valves that are in fluid communication with the first gas conduit. The first and second valves are configured in a parallel arrangement so that the first gas flows through the first valve and/or the second valve.

    摘要: This invention includes atomic layer deposition methods of depositing oxide comprising layers on substrates. In one implementation, a substrate is positioned within a deposition chamber. A first species is chemisorbed to form a first species monolayer onto the substrate within the deposition chamber from a gaseous first precursor. The chemisorbed first species is contacted with a gaseous second precursor effective to react with the first species to form an oxide of a component of the first species monolayer. The contacting at least in part results from flowing O3 to the deposition chamber, with the O3 being at a temperature of at least 170° C. at a location where it is emitted into the deposition chamber. The chemisorbing and the contacting are successively repeated to form an oxide comprising layer on the substrate. Additional aspects and implementations are contemplated.
