  • Publication number: 20250176255
    Abstract: Fabrication methods for integrated circuit (IC) structures and devices involving back-side nanoribbon removal are described herein. In one example, back-side nanoribbon removal involves providing stacks of nanoribbons from a first side of an IC structure, followed by removing one or more of the nanoribbons from a second side that is opposite the first side. In one example, an IC structure fabricated with back-side nanoribbon removal techniques may include a first stack of nanoribbons over a support and a second stack of nanoribbons over the support, where the number of nanoribbons in the first stack is less than in the second stack. A first transistor includes first channel regions in the nanoribbons of the first stack and a second transistor includes second channel regions in the nanoribbons of the second stack. Therefore, in one such example, the first transistor has channel regions in fewer nanoribbons than the second transistor.

  • Publication number: 20250159953
    Abstract: IC devices with angled transistors, and related assemblies and methods, are disclosed herein. A transistor is referred to as “angled” if a longitudinal axis of an elongated semiconductor structure (e.g., a fin or a nanoribbon) based on which the transistor is built is at an angle other than 0 degrees or 90 degrees with respect to edges of front or back faces of a support structure on/in which the transistor resides, e.g., at an angle between 10 degrees and 80 degrees with respect to at least one of such edges. Angled transistors provide a promising way to increasing densities of transistors on the limited real estate of semiconductor chips.
