    Abstract: Self-aligned gate edge trigate and finFET devices and methods of fabricating self-aligned gate edge trigate and finFET devices are described. In an example, a semiconductor structure includes a plurality of semiconductor fins disposed above a substrate and protruding through an uppermost surface of a trench isolation region. A gate structure is disposed over the plurality of semiconductor fins. The gate structure defines a channel region in each of the plurality of semiconductor fins. Source and drain regions are on opposing ends of the channel regions of each of the plurality of semiconductor fins, at opposing sides of the gate structure. The semiconductor structure also includes a plurality of gate edge isolation structures. Individual ones of the plurality of gate edge isolation structures alternate with individual ones of the plurality of semiconductor fins.

    Abstract: Confined epitaxial regions for semiconductor devices and methods of fabricating semiconductor devices having confined epitaxial regions are described. For example, a semiconductor structure includes a plurality of parallel semiconductor fins disposed above and continuous with a semiconductor substrate. An isolation structure is disposed above the semiconductor substrate and adjacent to lower portions of each of the plurality of parallel semiconductor fins. An upper portion of each of the plurality of parallel semiconductor fins protrudes above an uppermost surface of the isolation structure. Epitaxial source and drain regions are disposed in each of the plurality of parallel semiconductor fins adjacent to a channel region in the upper portion of the semiconductor fin. The epitaxial source and drain regions do not extend laterally over the isolation structure. The semiconductor structure also includes one or more gate electrodes, each gate electrode disposed over the channel region of one or more of the plurality of parallel semiconductor fins.
