  • Patent number: 11705518
    Abstract: Isolation schemes for gate-all-around (GAA) transistor devices are provided herein Integrated circuit structures including increased transistor source/drain contact area using a sacrificial source/drain layer are provided herein. In some cases, the isolation schemes include changing the semiconductor nanowires/nanoribbons in a targeted channel region between active or functional transistor devices to electrically isolate those active devices. The targeted channel region is referred to herein as a dummy channel region, as it is not used as an actual channel region for an active or functional transistor device. The semiconductor nanowires/nanoribbons in the dummy channel region can be changed by converting them to an electrical insulator and/or by adding dopant that is opposite in type relative to surrounding source/drain material (to create a p-n junction).

    Abstract: Interconnect structures are disclosed. An example includes conductive traces over a first dielectric layer, dielectric helmet structures over top surfaces of the conductive traces, and a second dielectric layer over the helmet structures. Spaces between adjacent ones of conductive traces are devoid of material. A bottom surface of the second dielectric layer is between top surfaces of the dielectric structures and bottom surfaces of the helmet structures, or co-planar with the top surface of the helmet structures, but the airgap extends above tops of the conductive traces. Another example includes a dielectric adjacent to upper sections but not lower sections of conductive traces, so as to provide airgaps between adjacent lower sections. Alternatively, a first dielectric material is adjacent the upper sections and a second compositionally different dielectric material is adjacent the lower sections. In either case, the sidewalls of the upper sections of the interconnect features may include scalloping.
