Abstract: A transition metal dichalcogenide (TMD) monolayer grown on a growth substrate is directly transferred to a target substrate. Eliminating the use of a carrier wafer in the TMD monolayer transfer process reduces the number of transfers endured by the TMD monolayer from two to one, which can result in less damage to the TMD monolayer. After a TMD monolayer is grown on a growth layer, a protective layer is formed on the TMD monolayer. The protective layer is bonded to the target substrate by a diffusion bonding layer. The direct transfer of TMD monolayers can be repeated to create a stack of TMD monolayers. A stack of TMD monolayers can be used in a field effect transistor, such as a nanoribbon field effect transistor.

Abstract: Hybrid bonding interconnect (HBI) architectures for scalability. Embodiments implement a bonding layer on a semiconductor die that includes a thick oxide layer overlaid with a thin layer of a hermetic material including silicon and at least one of carbon and nitrogen. The conductive bonds of the semiconductor die are placed in the thick oxide layer and exposed at the surface of the hermetic material. Some embodiments implement a non-bonding moisture seal ring (MSR) structure.

Abstract: A low strain transfer protective layer is formed on a transition metal dichalcogenide (TMD) monolayer to enable the transfer of the TMD monolayer from a growth substrate to a target substrate with little or no strain-induced damage to the TMD monolayer. Transfer of a TMD monolayer from a growth substrate to a target substrate comprises two transfers, a first transfer from the growth substrate to a carrier wafer and a second transfer from the carrier wafer to the target substrate. Transfer of the TMD monolayer from the growth substrate to the carrier wafer comprises mechanically lifting off the TMD monolayer from the growth substrate. The low strain transfer protective layer can limit the amount of strain transferred from the carrier wafer to the TMD monolayer during lift-off. The carrier wafer and protective layer are separated from the TMD monolayer after attachment of the TMD monolayer to the target substrate.

Abstract: Described herein are integrated circuit devices with conductive regions formed from MX or MAX materials. MAX materials are layered, hexagonal carbides and nitrides that include an early transition metal (M) and an A group element (A). MX materials remove the A group element. MAX and MX materials are highly conductive, and their two-dimensional layer structure allows very thin layers to be formed. MAX or MX materials can be used to form several conductive elements of IC circuits, including contacts, interconnects, or liners or barrier regions for contacts or interconnects.
