  • Patent number: 7368382
    Abstract: The invention includes an atomic layer deposition method of forming a layer of a deposited composition on a substrate. The method includes positioning a semiconductor substrate within an atomic layer deposition chamber. On the substrate, an intermediate composition monolayer is formed, followed by a desired deposited composition from reaction with the intermediate composition, collectively from flowing multiple different composition deposition precursors to the substrate within the deposition chamber. A material adheres to a chamber internal component surface from such sequentially forming. After such sequentially forming, a reactive gas flows to the chamber which is different in composition from the multiple different deposition precursors and which is effective to react with such adhering material. After the reactive gas flowing, such sequentially forming is repeated. Further implementations are contemplated.

  • Patent number: 7329615
    Abstract: 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.

  • Patent number: 7279398
    Abstract: The present disclosure provides methods and apparatus useful in depositing materials on batches of microfeature workpieces. One implementation provides a method in which a quantity of a first precursor gas is introduced to an enclosure at a first enclosure pressure. The pressure within the enclosure is reduced to a second enclosure pressure while introducing a purge gas at a first flow rate. The second enclosure pressure may approach or be equal to a steady-state base pressure of the processing system at the first flow rate. After reducing the pressure, the purge gas flow may be increased to a second flow rate and the enclosure pressure may be increased to a third enclosure pressure. Thereafter, a flow of a second precursor gas may be introduced with a pressure within the enclosure at a fourth enclosure pressure; the third enclosure pressure is desirably within about 10 percent of the fourth enclosure pressure.

  • Patent number: 7247561
    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.

    Abstract: The invention includes methods of utilizing supercritical fluids to introduce precursors into reaction chambers. In some aspects, a supercritical fluid is utilized to introduce at least one precursor into a chamber during ALD, and in particular aspects the supercritical fluid is utilized to introduce multiple precursors into the reaction chamber during ALD. The invention can be utilized to form any of various materials, including metal-containing materials, such as, for example, metal oxides, metal nitrides, and materials consisting of metal. Metal oxides can be formed by utilizing a supercritical fluid can be utilized to introduce a metal-containing precursor into reaction chamber, with the precursor then forming a metal-containing layer over a surface of a substrate. Subsequently, the metal-containing layer can be reacted with oxygen to convert at least some of the metal within the layer to metal oxide.

  • Publication number: 20060216933
    Abstract: The invention includes methods of forming films over substrates. A substrate is provided within a reaction chamber, and a mixture is also provided within the chamber. The mixture comprises a precursor of a desired material within a supercritical fluid. The precursor is relatively reactive under one set of conditions and is relatively non-reactive under another set of conditions. The precursor and supercritical fluid mixture is initially provided in the chamber under the conditions at which the precursor is relatively non-reactive. Subsequently, and while maintaining the supercritical state of the supercritical fluid, the conditions within the reaction chamber are changed to the conditions under which the precursor is relatively reactive. The precursor reacts to form the desired material, and at least some of the desired material forms a film on the substrate.
