Patent ID: 11923203
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A semiconductor device, comprising:
a first metal chalcogenide monolayer film disposed over a substrate;
a second metal chalcogenide monolayer film disposed over the first metal chalcogenide monolayer film;
wherein the first and second metal chalcogenide monolayer films each comprise a first metal and a chalcogen selected from the group consisting of S, Se, Te, and combinations thereof, and
wherein the second metal chalcogenide monolayer film is patterned so that portions of the first metal chalcogenide monolayer film are exposed through patterned portions of the second metal chalcogenide monolayer film; and
a metal layer disposed over portions of the first metal chalcogenide monolayer film exposed through the second metal chalcogenide monolayer film,
wherein the metal layer comprises a second metal, and
wherein the metal layer is chemically bonded to the first metal chalcogenide monolayer film.
