Abstract: An IC device may include a semiconductor structure and a backside semiconductor structure over the semiconductor structure. The semiconductor structure and backside semiconductor structure may constitute the source or drain region of a transistor. The backside semiconductor structure may be closer to the backside of a substrate of the IC device than the semiconductor structure. The backside semiconductor structure may be formed at a lower temperature than the semiconductor structure. The backside semiconductor structure may have one or more different materials from the semiconductor structure. For instance, a semiconductor material in the backside semiconductor structure may have a different crystal direction from a semiconductor material in the semiconductor structure. As another example, the backside semiconductor structure may have one or more different chemical compounds from the semiconductor structure. The backside semiconductor structure may be over a backside via that can couple the backside semiconductor structure to a backside metal layer.

Abstract: Fabrication methods for integrated circuit (IC) structures and devices with different nanoribbon thicknesses are disclosed. In one example, an IC structure includes a stack of nanoribbons stacked above one another over the support, including a first nanoribbon with a first channel region and a second nanoribbon with a second channel region, where the first channel region has a first thickness and the second channel region has a second thickness, and where the first thickness of the first channel region is different (e.g., greater) than the second thickness of the second channel region.

Abstract: An IC device with one or more transistors may also include one or more vias and jumpers for delivering power to the transistors. For instance, a via may be coupled to a power plane. A jumper may be connected to the via and an electrode of a transistor. With the via and jumper, an electrical connection is built between the power plane and the electrode. The via may be self-aligned. The IC device may include a dielectric structure at a first side of the via. A portion of the jumper may be at a second side of the via. The second side opposes the first side. The dielectric structure and the portion of the jumper may be over another dielectric structure that has a different dielectric material from the dielectric structure. The via may be insulated from another electrode of the transistor, which may be coupled to a ground plane.
