    Abstract: Embodiments herein describe techniques for an integrated circuit (IC). The IC may include a lower device layer that includes a first transistor structure, an upper device layer above the lower device layer including a second transistor structure, and an isolation wall that extends between the upper device layer and the lower device layer. The isolation wall may be in contact with an edge of a first gate structure of the first transistor structure and an edge of a second gate structure of the second transistor structure, and may have a first width to the edge of the first gate structure at the lower device layer, and a second width to the edge of the second gate structure at the upper device layer. The first width may be different from the second width. Other embodiments may be described and/or claimed.

    Abstract: Semiconductor nanowire devices having (111)-plane channel sidewalls and methods of fabricating semiconductor nanowire devices having (111)-plane channel sidewalls are described. For example, an integrated circuit structure includes a first semiconductor device including a plurality of vertically stacked nanowires disposed above a substrate, each of the nanowires comprising a discrete channel region having lateral sidewalls along a carrier transport direction. The integrated circuit structure also includes a second semiconductor device including a semiconductor fin disposed above the substrate, the semiconductor fin having a channel region with a top and side surfaces, the channel region having lateral sidewalls along a carrier transport direction.
