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

Claim 13:
14. A semiconductor device, comprising:
a channel region disposed over a first region of a semiconductor substrate,
wherein the channel region comprises one or more metal dichalcogenide monolayers;
source/drain regions disposed over second regions of the semiconductor substrate,
wherein the second regions of the semiconductor substrate are on opposing sides of the first region of the semiconductor substrate, and
wherein the source/drain regions comprise one or more metal chalcogenide monolayers, wherein each of the metal chalcogenide monolayers comprises a first metal and a chalcogen selected from the group consisting of S, Se, Te, and combinations thereof; and
a metal layer including a second metal disposed over the source/drain regions,
wherein the metal layer is chemically bonded to the metal chalcogenide monolayers in the second regions.
