  • Publication number: 20120202359
    Abstract: Methods for forming dielectric layers, and structures and devices resulting from such methods, and systems that incorporate the devices are provided. The invention provides an aluminum oxide/silicon oxide laminate film formed by sequentially exposing a substrate to an organoaluminum catalyst to form a monolayer over the surface, remote plasmas of oxygen and nitrogen to convert the organoaluminum layer to a porous aluminum oxide layer, and a silanol precursor to form a thick layer of silicon dioxide over the porous oxide layer. The process provides an increased rate of deposition of the silicon dioxide, with each cycle producing a thick layer of silicon dioxide of about 120 ? over the layer of porous aluminum oxide.

  • Publication number: 20110108929
    Abstract: Atomic layer deposition is enhanced using plasma. Plasma begins prior to flowing a second precursor into a chamber. The second precursor reacts with a first precursor to deposit a layer on a substrate. The layer may include at least one element from each of the first and second precursors. The layer may be TaN, and the precursors may be TaF5 and NE3. The plasma may begin during purge gas flow between a pulse of the first precursor and a pulse of the second precursor. Thermal energy assists the reaction of the precursors to deposit the layer on the substrate. The thermal energy may be greater than generally accepted for ALD (e.g., more than 300 degrees Celsius).

  • Patent number: 7838084
    Abstract: 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.

  • Patent number: 7611971
    Abstract: A method of reducing the amount of halogenated materials in a halogen-containing environment. The method comprises introducing an aluminum compound into the halogen-containing environment, reacting the aluminum compound with the halogenated material to form a gaseous reaction product, and removing the gaseous reaction product from the environment. The aluminum compound may be a trialkylaluminum compound, an alane, an alkylaluminum hydride, an alkylaluminum halide, an alkylaluminum sesquihalide, or an aluminum sesquihalide. The aluminum compound may alternatively form a solid aluminum product, which is deposited on a surface associated with the halogen-containing environment or onto a semiconductor disposed therewithin. The halogenated material is incorporated into the solid aluminum product, forming an inert film within which the halogenated material is trapped.
