Patent ID: 11929436
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A method of forming a semiconductor device, comprising:
forming a combination of an insulating matrix layer, a hydrogen-blocking dielectric barrier layer, and a gate electrode over a substrate, wherein the gate electrode overlies a horizontally-extending portion of the hydrogen-blocking dielectric barrier layer and is laterally surrounded by the insulating matrix layer, and wherein the hydrogen-blocking dielectric barrier layer comprises a first horizontally-extending portion that underlies the gate electrode;
forming a stack of a gate dielectric and a semiconducting metal oxide plate over the gate electrode and over horizontally-extending portions of the hydrogen-blocking dielectric barrier layer that overlie the insulating matrix layer; and
forming a source electrode and a drain electrode on end portions of the semiconducting metal oxide plate.
