  • Localized tunneling enhancement for semiconductor devices
    Patent number: 10636875
    Abstract: A semiconductor device includes a plurality of base layers. A tunneling layer is disposed on the plurality of base layers. A contact layer is disposed on the tunneling layer. An alloyed metal contact is annealed on to the contact layer. The alloyed metal contact forms a first region and a second region in the contact layer. The first region of the contact layer diffuses into the tunneling layer. The second region of the contact layer resides over the tunneling layer. The tunneling layer facilitates electron mobility of the second region.
