  • Publication number: 20210143051
    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.

  • Patent number: 10879241
    Abstract: Techniques are disclosed for controlling transistor sub-fin leakage. The techniques can be used for highly scaled finFETs, as well as other non-planar transistors. In some cases, the techniques include exposing a middle portion of a fin structure formed on a substrate and then converting the exposed portion to an electrically isolating material via a doping or oxidation process. For example, a monolayer doping (MLD) process may be used to deliver dopants to the exposed portion of the fin in a self-saturated monolayer scheme. In another example case, thermal oxidation may be used to convert the exposed portion to an insulator material. In some cases, a barrier layer (e.g., including carbon doping) may be located above the exposed portion of the fin to help prevent the doping or oxidation process from affecting the upper region of the fin, which is used for the transistor channel.

  • Publication number: 20200227413
    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.

  • Publication number: 20190164809
    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 insulating structure is directly adjacent sidewalls of the lower fin portion of the fin. A first gate electrode is over the upper fin portion and over a first portion of the insulating structure. A second gate electrode is over the upper fin portion and over a second portion of the insulating structure. A first dielectric spacer is along a sidewall of the first gate electrode. A second dielectric spacer is along a sidewall of the second gate electrode, the second dielectric spacer continuous with the first dielectric spacer over a third portion of the insulating structure between the first gate electrode and the second gate electrode.
