Abstract: Transistors and integrated circuitry including a 2D channel material layer within a stack of material layers further including one or more insulator (e.g., dielectric) materials above and/or below the 2D channel material layer. These supporting insulator layers may be non-sacrificial while other material layers within a starting material stack may be sacrificial, replaced, for example, with gate insulator and/or gate material. In some exemplary embodiments, the 2D channel material is a metal chalcogenide and the supporting insulator layer is advantageously a dielectric material composition having a low dielectric constant.

Abstract: A transistor structure includes a stack of nanoribbons spanning between terminals of the transistor. Ends of the nanoribbons include silicon, and channel regions between the ends include a transition metal and a chalcogen. A gate structure over the channel regions includes an insulator between the channel regions and a gate electrode material. Contact regions may be formed by modifying portions of the channel regions by adding a dopant to, or altering the crystal structure of, the channel regions.

Abstract: A transistor in an integrated circuit (IC) die includes source and drain terminals having a bulk material enclosed by a liner material. A nanoribbon channel region couples the source and drain terminals. The nanoribbon may include a transition metal and a chalcogen. The liner material may contact ends and upper and lower surfaces of the nanoribbon. The transistor may be in an interconnect layer. The source and drain terminals may be formed by conformally depositing the liner material over the ends of the nanoribbon and in voids opened in the IC die.

Abstract: Integrated circuit (IC) structures comprising transistors with metal chalcogenide channel material synthesized on a workpiece comprising a Group IV crystal. Prior to synthesis of the metal chalcogenide material, a passivation material is formed over the Group IV crystal to limit exposure of the substrate to the growth precursor gas(es) and thereby reduce a quantity of chalcogen species subsequently degassed from the workpiece. The passivation material may be applied to the front side, back side, and/or edge of a workpiece. The passivation material may be sacrificial or retained as a permanent feature of an IC structure. The passivation material may be advantageously amorphous and/or a compound comprising at least one of a metal or nitrogen that is good diffusion barrier and thermally stable at the metal chalcogenide synthesis temperatures.

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: A transistor structure includes a stack of nanoribbons coupling source and drain terminals. The nanoribbons may each include a pair of crystalline interface layers and a channel layer between the interface layers. The channel layers may be a molecular monolayer, including a metal and a chalcogen, with a thickness of less than 1 nm. The channel layers may be substantially monocrystalline, and the interface layers may be lattice matched to the channel layers. The channel layers may be epitaxially grown over the lattice-matched interface layers. The crystalline interface layers may be grown over sacrificial layers when forming the stack of nanoribbons.
