Abstract: Integrated circuit structures having backside contact stitching are described. In an example, an integrated circuit structure includes a first plurality of horizontally stacked nanowires laterally spaced apart from a second plurality of horizontally stacked nanowires. First and second epitaxial source or drain structure are at respective ends of the first and second pluralities of horizontally stacked nanowires. A conductive contact structure is beneath and in contact with the first epitaxial source or drain structure and the second epitaxial source or drain structure, and the conductive contact structure is continuous between the first and second epitaxial source or drain structures. The conductive contact structure has a first vertical thickness beneath the first and second epitaxial source or drain structures greater than a second vertical thickness in a region between the first and second epitaxial source or drain structures.

In an example, an integrated circuit structure includes a backbone including a lower backbone portion distinct from an upper backbone portion. A first vertical stack of nanowires is in lateral contact with a first side of the backbone. A second vertical stack of nanowires is in lateral contact with a second side of the backbone, the second side opposite the first side.

Abstract: Integrated circuit cell architectures including both front-side and back-side structures. One or more of back-side implant, semiconductor deposition, dielectric deposition, metallization, film patterning, and wafer-level layer transfer is integrated with front-side processing. Such double-side processing may entail revealing a back side of structures fabricated from the front-side of a substrate. Host-donor substrate assemblies may be built-up to support and protect front-side structures during back-side processing. Front-side devices, such as FETs, may be modified and/or interconnected during back-side processing. Electrical test may be performed from front and back sides of a workpiece. Back-side devices, such as FETs, may be integrated with front-side devices to expand device functionality, improve performance, or increase device density.

Abstract: Vertical integration schemes and circuit elements architectures for area scaling of semiconductor devices are described. In an example, an inverter structure includes a semiconductor fin separated vertically into an upper region and a lower region. A first plurality of gate structures is included for controlling the upper region of the semiconductor fin. A second plurality of gate structures is included for controlling the lower region of the semiconductor fin.

Abstract: Substrate-less diode, bipolar and feedthrough integrated circuit structures, and methods of fabricating substrate-less diode, bipolar and feedthrough integrated circuit structures, are described. For example, a substrate-less integrated circuit structure includes a semiconductor structure. A plurality of gate structures is over the semiconductor structure. A plurality of P-type epitaxial structures is over the semiconductor structure. A plurality of N-type epitaxial structures is over the semiconductor structure. One or more open locations is between corresponding ones of the plurality of gate structures. A backside contact is connected directly to one of the pluralities of P-type and N-type epitaxial structures.

Abstract: Gate-all-around integrated circuit structures having a removed substrate, and methods of fabricating gate-all-around integrated circuit structures having a removed substrate, are described. For example, an integrated circuit structure includes a vertical arrangement of horizontal nanowires. A gate stack surrounds a channel region of the vertical arrangement of horizontal nanowires. A pair of non-discrete epitaxial source or drain structures is at first and second ends of the vertical arrangement of horizontal nanowires. A pair of dielectric spacers is between the pair of non-discrete epitaxial source or drain structures and the gate stack. The pair of dielectric spacers and the gate stack have co-planar top surfaces. The pair of dielectric spacers, the gate stack and the pair of non-discrete epitaxial source or drain structures have co-planar bottom surfaces.

Abstract: Embodiments herein describe techniques for a semiconductor device including a first transistor stacked above and self-aligned with a second transistor, where a shadow of the first transistor substantially overlaps with the second transistor. The first transistor includes a first gate electrode, a first channel layer including a first channel material and separated from the first gate electrode by a first gate dielectric layer, and a first source electrode coupled to the first channel layer. The second transistor includes a second gate electrode, a second channel layer including a second channel material and separated from the second gate electrode by a second gate dielectric layer, and a second source electrode coupled to the second channel layer. The second source electrode is self-aligned with the first source electrode, and separated from the first source electrode by an isolation layer. Other embodiments may be described and/or claimed.
