Patents by Inventor Keith R. Hampton

Keith R. Hampton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8703588
    Abstract: A phase change material including a high adhesion phase change material formed on a dielectric material and a low adhesion phase change material formed on the high adhesion phase change material. The high adhesion phase change material includes a greater amount of at least one of nitrogen and oxygen than the low adhesion phase change material. The phase change material is produced by forming a first chalcogenide compound material including an amount of at least one of nitrogen and oxygen on the dielectric material and forming a second chalcogenide compound including a lower percentage of at least one of nitrogen and oxygen on the first chalcogenide compound material. A phase change random access memory device, and a semiconductor structure are also disclosed.
    Type: Grant

  • Patent number: 8481359
    Abstract: Methods of forming a phase change material are disclosed. The method includes forming a chalcogenide compound on a substrate and simultaneously applying a bias voltage to the substrate to alter the stoichiometry of the chalcogenide compound. In another embodiment, the method includes positioning a substrate and a deposition target having a first stoichiometry in a deposition chamber. A plasma is generated in the deposition chamber to form a phase change material on the substrate. The phase change material has a stoichiometry similar to the first stoichiometry. A bias voltage is applied to the substrate to convert the stoichiometry of the phase change material to a second stoichiometry. A phase change material, a phase change random access memory device, and a semiconductor structure are also disclosed.
