摘要: Embodiments herein describe techniques for a semiconductor device including a first transistor (120) stacked above and self-aligned with a second transistor (110), where a shadow of the first transistor substantially overlaps with the second transistor. The first transistor includes a first gate electrode (129), a first channel layer (123) including a first channel material and separated from the first gate electrode by a first gate dielectric layer (128), and a first source electrode (125) coupled to the first channel layer. The second transistor includes a second gate electrode (109), a second channel layer (103) including a second channel material and separated from the second gate electrode by a second gate dielectric layer (108), and a second source electrode coupled to the second channel layer.

摘要: Gate-all-around integrated circuit structures having depopulated channel structures, and methods of fabricating gate-all-around integrated circuit structures having depopulated channel structures using a bottom-up oxidation approach, are described. For example, an integrated circuit structure includes a vertical arrangement of nanowires above a substrate. The vertical arrangement of nanowires has one or more active nanowires (304C, 304D, 314A-314D) above one or more oxidized nanowires (350A, 230B). A gate stack is over the vertical arrangement of nanowires and around the one or more oxidized nanowires.

摘要: Embodiments herein describe techniques for a semiconductor device including a carrier wafer, and an integrated circuit (IC) formed on a device wafer bonded to the carrier wafer. The IC includes a front end layer having one or more transistors at front end of the device wafer, and a back end layer having a metal interconnect coupled to the one or more transistors. One or more gaps may be formed by removing components of the one or more transistors. Furthermore, the IC includes a capping layer at backside of the device wafer next to the front end layer of the device wafer, filling at least partially the one or more gaps of the front end layer. Moreover, the IC includes one or more air gaps formed within the one or more gaps, and between the capping layer and the back end layer. Other embodiments may be described and/or claimed.

摘要: Gate-all-around integrated circuit structures having depopulated channel structures, and methods of fabricating gate-all-around integrated circuit structures having depopulated channel structures using multiple bottom-up oxidation approaches, are described. For example, an integrated circuit structure includes a first vertical arrangement of nanowires comprising oxide nanowires (350A, 350B, 350C). A second vertical arrangement of nanowires above the first vertical arrangement of nanowires comprises active nanowires (314A, 314B, 314C, 314D).

摘要: Integrated circuitry comprising transistor structures having a channel portion over a base portion of fin. The base portion of the fin is an insulative amorphous oxide, or a counter-doped crystalline material. Transistor structures, such as channel portions of a fin and source and drain materials may be first formed with epitaxial processes seeded by a front side of a crystalline substrate. Following front side processing, a backside of the transistor structures may be exposed and the base portion of the fin modified from the crystalline substrate composition into the amorphous oxide or counter-doped crystalline material using backside processes and low temperatures that avoid degradation to the channel material while reducing transistor off-state leakage.

摘要: Integrated circuitry comprising interconnect metallization on both front and back sides of a gate-all-around (GAA) transistor structure lacking at least one active bottom channel region. Bottom channel regions may be depopulated from a GAA transistor structure following removal of a back side substrate that exposes an inactive portion of a semiconductor fin. During back-side processing, one or more bottom channel region may be removed or rendered inactive through dopant implantation. Back-side processing may then proceed with the interconnection of one or more terminal of the GAA transistor structures through one or more levels of back-side interconnect metallization.

摘要: Gate-all-around integrated circuit structures having an insulator fin on an insulator substrate, and methods of fabricating gate-all-around integrated circuit structures having an insulator fin on an insulator substrate, are described. For example, an integrated circuit structure includes an insulator fin on an insulator substrate. A vertical arrangement of horizontal semiconductor nanowires is over the insulator fin. A gate stack surrounds a channel region of the vertical arrangement of horizontal semiconductor nanowires, and the gate stack is overlying the insulator fin. A pair of epitaxial source or drain structures is at first and second ends of the vertical arrangement of horizontal semiconductor nanowires and at first and second ends of the insulator fin.
