Abstract: A group III-N nanowire is disposed on a substrate. A longitudinal length of the nanowire is defined into a channel region of a first group III-N material, a source region electrically coupled with a first end of the channel region, and a drain region electrically coupled with a second end of the channel region. A second group III-N material on the first group III-N material serves as a charge inducing layer, and/or barrier layer on surfaces of nanowire. A gate insulator and/or gate conductor coaxially wraps completely around the nanowire within the channel region. Drain and source contacts may similarly coaxially wrap completely around the drain and source regions.

Abstract: An interlayer is used to reduce Fermi-level pinning phenomena in a semiconductive device with a semiconductive substrate. The interlayer may be a rare-earth oxide. The interlayer may be an ionic semiconductor. A metallic barrier film may be disposed between the interlayer and a metallic coupling. The interlayer may be a thermal-process combination of the metallic barrier film and the semiconductive substrate. A process of forming the interlayer may include grading the interlayer. A computing system includes the interlayer.

Abstract: An embodiment of the invention includes an epitaxial layer that directly contacts, for example, a nanowire, fin, or pillar in a manner that allows the layer to relax with two or three degrees of freedom. The epitaxial layer may be included in a channel region of a transistor. The nanowire, fin, or pillar may be removed to provide greater access to the epitaxial layer. Doing so may allow for a “all-around gate” structure where the gate surrounds the top, bottom, and sidewalls of the epitaxial layer. Other embodiments are described herein.

Abstract: A capacitor device, such as a metal insulator metal (MIM) capacitor includes a seed layer including tantalum, a first electrode on the seed layer, where the first electrode includes at least one of ruthenium or iridium and an insulator layer on the seed layer, where the insulator layer includes oxygen and one or more of Sr, Ba or Ti. In an exemplary embodiment, the insulator layer is a crystallized layer having a substantially smooth surface. A crystallized insulator layer having a substantially smooth surface facilitates low electrical leakage in the MIM capacitor. The capacitor device further includes a second electrode layer on the insulator layer, where the second electrode layer includes a second metal or a second metal alloy.

Abstract: Thin film transistor structures may include a regrown source or drain material between a channel material and source or drain contact metallization. The source or drain material may be selectively deposited at low temperatures to backfill recesses formed in the channel material. Electrically active dopant impurities may be introduced in-situ during deposition of the source or drain material. The source or drain material may overlap a portion of a gate electrode undercut by the recesses. With channel material of a first composition and source or drain material of a second composition, thin film transistor structures may display low external resistance and high channel mobility.

Abstract: Embodiments herein describe techniques, systems, and method for a semiconductor device. A semiconductor device may include isolation areas above a substrate to form a trench between the isolation areas. A first buffer layer is over the substrate, in contact with the substrate, and within the trench. A second buffer layer is within the trench over the first buffer layer, and in contact with the first buffer layer. A channel area is above the first buffer layer, above a portion of the second buffer layer that are below a source area or a drain area, and without being vertically above a portion of the second buffer layer. In addition, the source area or the drain area is above the second buffer layer, in contact with the second buffer layer, and adjacent to the channel area. Other embodiments may be described and/or claimed.

Abstract: A metal chalcogenide material layer of lower quality provides a transition between a metal chalcogenide material layer of higher quality and a gate insulator material that separates the metal chalcogenide material layers from a gate electrode of a metal-oxide semiconductor field effect transistor (MOSFET) structure. Gate insulator material may be more readily initiated and/or or precisely controlled to a particular thickness when formed on lower quality metal chalcogenide material. Accordingly, such a material stack may be integrated into a variety of transistor structures, including multi-gate, multi-channel nanowire or nanosheet transistor structures.

Abstract: Adjacent interconnect lines are in staggered, vertically spaced positions, which accordingly reduces their capacitive coupling within one level of interconnect metallization. Short and tall interconnect via openings are landed on the vertically staggered interconnect lines. Cap material selectively deposited upon upper ones of the staggered interconnect lines limits over etch of the short vias while the tall vias are advanced toward lower ones of the staggered interconnect lines. The via openings of differing depth may be filled, for example with a single damascene metallization process that defines a co-planar top surface for all via metallization over the staggered, vertically spaced interconnect lines.
