    Abstract: A FinFET has shaped epitaxial structures for the source and drain that are electrically isolated from the substrate. Shaped epitaxial structures in the active region are separated from the substrate in the source and drain regions while those in the channel region remain. The gaps created by the separation in the source and drain are filled with electrically insulating material. Prior to filling the gaps, defects created by the separation may be reduced.

  • Patent number: 10032911
    Abstract: Techniques are disclosed for forming a GaN transistor on a semiconductor substrate. An insulating layer forms on top of a semiconductor substrate. A trench, filled with a trench material comprising a III-V semiconductor material, forms through the insulating layer and extends into the semiconductor substrate. A channel structure, containing III-V material having a defect density lower than the trench material, forms directly on top of the insulating layer and adjacent to the trench. A source and drain form on opposite sides of the channel structure, and a gate forms on the channel structure. The semiconductor substrate forms a plane upon which both GaN transistors and other transistors can form.
