Abstract: Trench-confined selective epitaxial growth process in which epitaxial growth of a semiconductor device layer proceeds within the confines of a trench. In embodiments, a trench is fabricated to include a pristine, planar semiconductor seeding surface disposed at the bottom of the trench. Semiconductor regions around the seeding surface may be recessed relative to the seeding surface with Isolation dielectric disposed there on to surround the semiconductor seeding layer and form the trench. In embodiments to form the trench, a sacrificial hardmask fin may be covered in dielectric which is then planarized to expose the hardmask fin, which is then removed to expose the seeding surface. A semiconductor device layer is formed from the seeding surface through selective heteroepitaxy. In embodiments, non-planar devices are formed from the semiconductor device layer by recessing a top surface of the isolation dielectric. In embodiments, non-planar devices CMOS devices having high carrier mobility may be made from the semiconductor device layer.

Abstract: 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.

Abstract: III-N transistors with epitaxial semiconductor heterostructures having steep subthreshold slope are described. In embodiments, a III-N HFET employs a gate stack with balanced and opposing III-N polarization materials. Overall effective polarization of the opposing III-N polarization materials may be modulated by an external field, for example associated with an applied gate electrode voltage. In embodiments, polarization strength differences between the III-N materials within the gate stack are tuned by composition and/or film thickness to achieve a desired transistor threshold voltage (Vt). With polarization strengths within the gate stack balanced and opposing each other, both forward and reverse gate voltage sweeps may generate a steep sub-threshold swing in drain current as charge carriers are transferred to and from the III-N polarization layers and the III-N channel semiconductor.

Abstract: Deep gate-all-around semiconductor devices having germanium or group III-V active layers are described. For example, a non-planar semiconductor device includes a hetero-structure disposed above a substrate. The hetero-structure includes a hetero-junction between an upper layer and a lower layer of differing composition. An active layer is disposed above the hetero-structure and has a composition different from the upper and lower layers of the hetero-structure. A gate electrode stack is disposed on and completely surrounds a channel region of the active layer, and is disposed in a trench in the upper layer and at least partially in the lower layer of the hetero-structure. Source and drain regions are disposed in the active layer and in the upper layer, but not in the lower layer, on either side of the gate electrode stack.

Abstract: Techniques are disclosed for providing a low resistance self-aligned contacts to devices formed in a semiconductor heterostructure. The techniques can be used, for example, for forming contacts to the gate, source and drain regions of a quantum well transistor fabricated in III-V and SiGe/Ge material systems. Unlike conventional contact process flows which result in a relatively large space between the source/drain contacts to gate, the resulting source and drain contacts provided by the techniques described herein are self-aligned, in that each contact is aligned to the gate electrode and isolated therefrom via spacer material.

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.
