摘要:
A transistor that is formed with a transition metal dichalcogenide material is provided. The transition metal dichalcogenide material is formed using a direct deposition process and patterned into one or more fins. A gate dielectric and a gate electrode are formed over the one or more fins. Alternatively, the transition metal dichalcogenide material may be formed using a deposition of a non-transition metal dichalcogenide material followed by a treatment to form a transition metal dichalcogenide material. Additionally, fins that utilized the transition metal dichalcogenide material may be formed with sidewalls that are either perpendicular to a substrate or else are sloped relative to the substrate.
