    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.

    Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, 10 nanometer node and smaller integrated circuit structure fabrication and the resulting structures. In an example, an integrated circuit structure includes a fin comprising silicon, the fin having a lower fin portion and an upper fin portion. A first insulating layer is directly on sidewalls of the lower fin portion of the fin, wherein the first insulating layer is a non-doped insulating layer comprising silicon and oxygen. A second insulating layer is directly on the first insulating layer directly on the sidewalls of the lower fin portion of the fin, the second insulating layer comprising silicon and nitrogen. A dielectric fill material is directly laterally adjacent to the second insulating layer directly on the first insulating layer directly on the sidewalls of the lower fin portion of the fin.

    Abstract: Semiconductor devices having fin-end stress-inducing features, and methods of fabricating semiconductor devices having fin-end stress-inducing features, are described. In an example, a semiconductor structure includes a semiconductor fin protruding through a trench isolation region above a substrate. The semiconductor fin has a top surface, a first end, a second end, and a pair of sidewalls between the first end and the second end. A gate electrode is over a region of the top surface and laterally adjacent to a region of the pair of sidewalls of the semiconductor fin. The gate electrode is between the first end and the second end of the semiconductor fin. A first dielectric plug is at the first end of the semiconductor fin. A second dielectric plug is at the second end of the semiconductor fin.

    Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, 10 nanometer node and smaller integrated circuit structure fabrication and the resulting structures. In an example, an integrated circuit structure includes a fin. An isolation structure surrounds a lower fin portion, the isolation structure comprising an insulating material having a top surface, and a semiconductor material on a portion of the top surface of the insulating material, wherein the semiconductor material is separated from the fin. A gate dielectric layer is over the top of an upper fin portion and laterally adjacent the sidewalls of the upper fin portion, the gate dielectric layer further on the semiconductor material on the portion of the top surface of the insulating material. A gate electrode is over the gate dielectric layer.
