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: An integrated circuit (IC) device includes a stripe of material perpendicular to, and spanning between, semiconductor structures with multiple widths, and the stripe is between transistors with channel regions of differing widths in the semiconductor structures. The material stripes cover transition portions between different widths of the semiconductor structures. The semiconductor structures may be channel structures of different types, including groups of fins or nanoribbons. Channel regions of differing widths may include more or fewer fins or narrower or wider nanoribbons. The channel regions may have alternating conductivity types, n- and p-type.

Abstract: Described is a ferroelectric-based capacitor that improves reliability of a ferroelectric memory by providing tensile stress along a plane (e.g., x-axis) of a ferroelectric or anti-ferroelectric material of the ferroelectric/anti-ferroelectric based capacitor. Tensile stress is provided by a spacer comprising metal, semimetal, or oxide (e.g., metal or oxide of one or more of: Al, Ti, Hf, Si, Ir, or N). The tensile stress provides polar orthorhombic phase to the ferroelectric material and tetragonal phase to the anti-ferroelectric material. As such, memory window and reliability of the ferroelectric/anti-ferroelectric oxide thin film improves.

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. The transistor structure may be in an integrated circuit device.

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: Described herein are ferroelectric (FE) memory cells that include transistors having gate stacks separate from FE capacitors of these cells. An example memory cell may be implemented as an IC device that includes a support structure (e.g., a substrate) and a transistor provided over the support structure and including a gate stack. The IC device also includes a FE capacitor having a first capacitor electrode, a second capacitor electrode, and a capacitor insulator of a FE material between the first capacitor electrode and the second capacitor electrode, where the FE capacitor is separate from the gate stack (i.e., is not integrated within the gate stack and does not have any layers that are part of the gate stack). The IC device further includes an interconnect structure, configured to electrically couple the gate stack and the first capacitor electrode.

Abstract: Techniques are provided herein to form semiconductor devices having epitaxial growth laterally extending between inner spacer structures to mitigate issues caused by the inner spacer structures either being too thick or too thin. A directional etch is performed along the side of a multilayer fin to create a relatively narrow opening for a source or drain region to increase the usable fin space for forming the inner spacer structures. After the inner spacer structures are formed around ends of the semiconductor layers within the fin, the exposed ends of the semiconductor layers are laterally recessed inwards from the outermost sidewalls of the inner spacer structures. Accordingly, the epitaxial source or drain region is grown from the recessed semiconductor ends and thus fills in the recessed regions between the spacer structures.
