  • Patent number: 11961722
    Abstract: A method and apparatus are for controlling stress variation in a material layer formed via pulsed DC physical vapour deposition. The method includes the steps of providing a chamber having a target from which the material layer is formed and a substrate upon which the material layer is formable, and subsequently introducing a gas within the chamber. The method further includes generating a plasma within the chamber and applying a first magnetic field proximate the target to substantially localise the plasma adjacent the target. An RF bias is applied to the substrate to attract gas ions from the plasma toward the substrate and a second magnetic field is applied proximate the substrate to steer gas ions from the plasma to selective regions upon the material layer formed on the substrate.
    Type: Grant

  • Patent number: 8454805
    Abstract: A method of depositing an amorphous layer of AlON includes providing an aluminum sputter target in a chamber, exposing the target and chamber to O2 to saturate the exposed surfaces with oxygen, introducing a substrate into the chamber in an atmosphere containing at least nitrogen and oxygen, and sputtering the target in the nitrogen and oxygen atmosphere to deposit an amorphous AlON film.

  • Patent number: 8337675
    Abstract: A method induces plasma vapor deposition of metal into a recess in a workpiece. The method achieves re-sputtering of the metal at the base of the recess with a sputter gas by utilizing a mixture of Ar and He and/or Ne as the sputter gas with a ratio of He and/or Ne:Ar of at least about 10:1.
