Abstract: Metal insulator metal capacitors are described. In an example, a metal-insulator-metal (MIM) capacitor includes a first electrode that includes a bottom region and a pair of vertical regions. First metal layers are outside the vertical regions and in contact with the vertical regions. An insulator is over the first electrode. A second electrode is over the insulator. A second metal layer is on a top surface of the second electrode.

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.
