Abstract: Transistor structures having channel regions comprising alternating layers of compressively and tensilely strained epitaxial materials are provided. The alternating epitaxial layers can form channel regions in single and multigate transistor structures. In alternate embodiments, one of the two alternating layers is selectively etched away to form nanoribbons or nanowires of the remaining material. The resulting strained nanoribbons or nanowires form the channel regions of transistor structures. Also provided are computing devices comprising transistors comprising channel regions comprised of alternating compressively and tensilely strained epitaxial layers and computing devices comprising transistors comprising channel regions comprised of strained nanoribbons or nanowires.

Abstract: An embodiment uses a very thin layer nanostructure (e.g., a Si or SiGe fin) as a template to grow a crystalline, non-lattice matched, epitaxial (EPI) layer. In one embodiment the volume ratio between the nanostructure and EPI layer is such that the EPI layer is thicker than the nanostructure. In some embodiments a very thin bridge layer is included between the nanostructure and EPI. An embodiment includes a CMOS device where EPI layers covering fins (or that once covered fins) are oppositely polarized from one another. An embodiment includes a CMOS device where an EPI layer covering a fin (or that once covered a fin) is oppositely polarized from a bridge layer covering a fin (or that once covered a fin). Thus, various embodiments are disclosed from transferring defects from an EPI layer to a nanostructure (that is left present or removed). Other embodiments are described herein.

Abstract: Techniques are disclosed for an integrated circuit including a ferroelectric gate stack including a ferroelectric layer, an interfacial oxide layer, and a gate electrode. The ferroelectric layer can be voltage activated to switch between two ferroelectric states. Employing such a ferroelectric layer provides a reduction in leakage current in an off-state and provides an increase in charge in an on-state. The interfacial oxide layer can be formed between the ferroelectric layer and the gate electrode. Alternatively, the ferroelectric layer can be formed between the interfacial oxide layer and the gate electrode.

Abstract: Integrated circuit (IC) including transistors with high-mobility/high-saturation velocity, non-silicon channel materials coupled to a silicon substrate through counter-doped sub-channel materials, which greatly reduce electrical leakage currents through the substrate when the IC is operated at very low temperatures (e.g., below −25 C). With low temperature operation, high transistor performance associated with the non-silicon channel materials can be integrated into high density IC architectures that avoid the limitations associated with semiconductor material layer transfers.

Abstract: Embodiments herein describe techniques for a three dimensional transistor above a substrate. A three dimensional transistor includes a channel structure, where the channel structure includes a channel material and has a source area, a drain area, and a channel area between the source area and the drain area. A source electrode is coupled to the source area, a drain electrode is coupled to the drain area, and a gate electrode is around the channel area. An electrode selected from the source electrode, the drain electrode, or the gate electrode is in contact with the channel material on a sidewall of an opening in an inter-level dielectric layer or a surface of the electrode.

Abstract: Gate-all-around integrated circuit structures having depopulated channel structures, and methods of fabricating gate-all-around integrated circuit structures having depopulated channel structures using multiple bottom-up oxidation approaches, are described. For example, an integrated circuit structure includes a vertical arrangement of nanowires. All nanowires of the vertical arrangement of nanowires are oxide nanowires. A gate stack is over the vertical arrangement of nanowires, around each of the oxide nanowires. The gate stack includes a conductive gate electrode.
