    摘要: 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.

    摘要: 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.
