摘要： Embodiments of the present disclosure describe multi-device flexible systems on a chip (SOCs) and methods for making such SOCs. A multi-material stack may be processed sequentially to form multiple integrated circuit (IC) devices in a single flexible SOC. By forming the IC devices from a single stack, it is possible to form contacts for multiple devices through a single metallization process and for those contacts to be located in a common back-plane of the SOC. Stack layers may be ordered and processed according to processing temperature, such that higher temperature processes are performed earlier. In this manner, intervening layers of the stack may shield some stack layers from elevated processing temperatures associated with processing upper layers of the stack. Other embodiments may be described and/or claimed.

摘要： Nanowire-based gate all-around transistor devices having one or more active nanowires and one or more inactive nanowires are described herein. Methods to fabricate such devices are also described. One or more embodiments of the present invention are directed at approaches for varying the gate width of a transistor structure comprising a nanowire stack having a distinct number of nanowires. The approaches include rendering a certain number of nanowires inactive (i.e. so that current does not flow through the nanowire), by severing the channel region, burying the source and drain regions, or both. Overall, the gate width of nanowire-based structures having a plurality of nanowires may be varied by rendering a certain number of nanowires inactive, while maintaining other nanowires as active.

摘要： 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 (10 10) plane on a (110) plane of the silicon.

摘要： 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.

摘要： 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.
