Patents by Inventor Andrew Metz

Andrew Metz 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: 9368368
    Abstract: Techniques herein include methods for etching an oxide layer with greater selectivity to underlying channel materials. Such an increase in etch selectivity reduces damage to channel materials thereby providing more reliable and better performing semiconductor devices. Techniques herein include using fluorocarbon gas to feed a plasma to create etchants, and also creating a flux of ballistic electrons to treat a given substrate during an etch process.
    Type: Grant

    Date of Patent: June 14, 2016
    Assignee: Tokyo Electron Limited
    Inventor: Andrew Metz
  • Patent number: 9257529
    Abstract: Techniques disclosed herein provide a gate pitch scaling solution for creating source/drain contacts in a replacement metal gate fabrication scheme. Such techniques provide a self-aligned contact process that protects gate electrodes from shorts due to etching from misaligned patterns. Techniques herein provide a dual layer cap formed by making a semi conformal material deposition over a non-planar topography of RMG formation structures, and using selective etching and planarization to yield a dual layer protective cap that does not excessively increase an aspect ratio.
