Abstract: Described herein are transistors with monolayer transition metal dichalcogenides (TMD) semiconductor material. TMD materials include combination of a transition metal (e.g., molybdenum or tungsten) and a chalcogen (e.g., sulfur or selenium) in a monolayer having a hexagonal crystal structure. A transistor has a single layer of TMD forming a channel region, and multiple layers of the TMD material at the source and drain regions. Upper portions of the multilayer TMD source and drain regions are doped, and conductive contacts are formed over the doped portions.

Abstract: A transistor has multiple channel regions coupling source and drain structures, and a seed material is between one of the source or drain structures and a channel material, which includes a metal and a chalcogen. Each channel region may include a nanoribbon. A nanoribbon may have a monocrystalline structure and a thickness of a monolayer, less than 1 nm. A nanoribbon may be free of internal grain boundaries. A nanoribbon may have an internal grain boundary adjacent an end opposite the seed material. The seed material may directly contact the first of the source or drain structures, and the channel material may directly contact the second of the source or drain structures.

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: Techniques and mechanisms for forming a gate dielectric structure and source or drain (S/D) structures on a monolayer channel structure of a transistor. In an embodiment, the channel structure comprises a two-dimensional (2D) layer of a transition metal dichalcogenide (TMD) material. During fabrication of the transistor structure, a layer of a dielectric material is deposited on the channel structure, wherein the dielectric material is suitable to provide a reaction, with a plasma, to produce a conductive material. While a first portion of the dielectric material is covered by a patterned structure, a second portion of the dielectric material is exposed to a plasma treatment to form a source or dielectric (S/D) electrode structure that adjoins the first portion. In another embodiment, the dielectric material is an oxide of a Group V-VI transition metal.

Abstract: Techniques and mechanisms for providing gate dielectric structures of a transistor. In an embodiment, the transistor comprises a thin channel structure which comprises one or more layers of a transition metal dichalcogenide (TMD) material. The channel structure forms two surfaces on opposite respective sides thereof, wherein the surfaces extend to each of two opposing edges of the channel structure. A composite gate dielectric structure comprises first bodies of a first dielectric material, wherein the first bodies each adjoin a different respective one of the two opposing edges, and variously extend to each of the surfaces two surfaces. The composite gate dielectric structure further comprises another body of a second dielectric material other than the first dielectric material. In another embodiment, the other body adjoins one or both of the two surfaces, and extends along one or both of the two surfaces to each of the first bodies.
