Abstract: Fin trim plug structures with metal for imparting channel stress are described. In an example, an integrated circuit structure includes a fin including silicon, the fin having a top and sidewalls, wherein the top has a longest dimension along a direction. A first isolation structure is over a first end of the fin. A gate structure including a gate electrode is over the top of and laterally adjacent to the sidewalls of a region of the fin. The gate structure is spaced apart from the first isolation structure along the direction. A second isolation structure is over a second end of the fin, the second end opposite the first end, the second isolation structure spaced apart from the gate structure along the direction. The first isolation structure and the second isolation structure both include a dielectric material laterally surrounding an isolated metal structure.

Abstract: Embodiments described herein may be related to forming nano ribbon transistors using layered 2D semiconductor channels. The layered 2D semiconductor channels may be created by forming a scaffold structure that has a first edge that extends from a silicon-based substrate, and a second edge opposite the first edge that is distal to the silicon based substrate. Alternating layers of 2D semiconductor material and a 3D semiconductor material may then be built on the second edge of the scaffold structure. In embodiments, the 3D semiconductor material may then be removed and a gate material deposited around at least a portion of the layers of 2D semiconductor material.

Abstract: Techniques and mechanisms for providing electrical insulation or other protection of an integrated circuit (IC) device with a spacer structure which comprises an (anti)ferromagnetic material. In an embodiment, a transistor comprises doped source or drain regions and a channel region which are each disposed in a fin structure, wherein a gate electrode and an underlying dielectric layer of the transistor each extend over the channel region. Insulation spacers are disposed on opposite sides of the gate electrode, where at least a portion of one such insulation spacer comprises an (anti)ferroelectric material. Another portion of the insulation spacer comprises a non-(anti)ferroelectric material. In another embodiment, the two portions of the spacer are offset vertically from one another, wherein the (anti)ferroelectric portion forms a bottom of the spacer.
