Abstract: Architectures and techniques for co-integration of heterogeneous materials, such as group III-V semiconductor materials and group IV semiconductors (e.g., Ge) on a same substrate (e.g. silicon). In embodiments, multi-layer heterogeneous semiconductor material stacks having alternating nanowire and sacrificial layers are employed to release nanowires and permit formation of a coaxial gate structure that completely surrounds a channel region of the nanowire transistor. In embodiments, individual PMOS and NMOS channel semiconductor materials are co-integrated with a starting substrate having a blanket layers of alternating Ge/III-V layers. In embodiments, vertical integration of a plurality of stacked nanowires within an individual PMOS and individual NMOS device enable significant drive current for a given layout area.

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: Transistor structures including a non-planar body that has an active portion comprising a semiconductor material of a first height that is variable, and an inactive portion comprising an oxide of the semiconductor material of a second variable height, complementary to the first height. Gate electrodes and source/drain terminals may be coupled through a transistor channel having any width that varies according to the first height. Oxidation of a semiconductor material may be selectively catalyzed to convert a desired portion of a non-planar body into the oxide of the semiconductor material. Oxidation may be enhanced through the application of a catalyst, such as one comprising metal and oxygen, for example.

Abstract: System on Chip (SoC) solutions integrating an RFIC with a PMIC using a transistor technology based on group III-nitrides (III-N) that is capable of achieving high Ft and also sufficiently high breakdown voltage (BV) to implement high voltage and/or high power circuits. In embodiments, the III-N transistor architecture is amenable to scaling to sustain a trajectory of performance improvements over many successive device generations. In embodiments, the III-N transistor architecture is amenable to monolithic integration with group IV transistor architectures, such as planar and non-planar silicon CMOS transistor technologies. Planar and non-planar HEMT embodiments having one or more of recessed gates, symmetrical source and drain, regrown source/drains are formed with a replacement gate technique permitting enhancement mode operation and good gate passivation.

Abstract: Transistors for high voltage and high frequency operation. A non-planar, polar crystalline semiconductor body having a top surface disposed between first and second opposite sidewalls includes a channel region with a first crystalline semiconductor layer disposed over the first and second sidewalls. The first crystalline semiconductor layer is to provide a two dimensional electron gas (2DEG) within the channel region. A gate structure is disposed over the first crystalline semiconductor layer along at least the second sidewall to modulate the 2DEG. First and second sidewalls of the non-planar polar crystalline semiconductor body may have differing polarity, with the channel proximate to a first of the sidewalls. The gate structure may be along a second of the sidewalls to gate a back barrier. The polar crystalline semiconductor body may be a group III-nitride formed on a silicon substrate with the (1010) plane on a (110) plane of the silicon.
