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: Contact over active gate structure with metal oxide layers are described are described. In an example, an integrated circuit structure includes a plurality of gate structures above substrate, each of the gate structures including a gate insulating layer thereon. A plurality of conductive trench contact structures is alternating with the plurality of gate structures. A portion of one of the plurality of trench contact structures has a metal oxide layer thereon. An interlayer dielectric material is over the plurality of gate structures and over the plurality of conductive trench contact structures. An opening is in the interlayer dielectric material and in a gate insulating layer of a corresponding one of the plurality of gate structures. A conductive via is in the opening, the conductive via in direct contact with the corresponding one of the plurality of gate structures, and the conductive via on the metal oxide layer.

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 first plurality of semiconductor fins having a longest dimension along a first direction. Adjacent individual semiconductor fins of the first plurality of semiconductor fins are spaced apart from one another by a first amount in a second direction orthogonal to the first direction. A second plurality of semiconductor fins has a longest dimension along the first direction. Adjacent individual semiconductor fins of the second plurality of semiconductor fins are spaced apart from one another by the first amount in the second direction, and closest semiconductor fins of the first plurality of semiconductor fins and the second plurality of semiconductor fins are spaced apart by a second amount in the second direction
