摘要: A new MOSFET device is described comprising a metal gate electrode, a gate dielectric and an interfacial layer. The interfacial layer comprises a lanthanum hafnium oxide material for modulating the effective work function of the metal gate. The gate dielectric material in contact with the interfacial layer is different that the interfacial layer material. A method for its manufacture is also provided and its applications.

摘要: A new MOSFET device is described comprising a metal gate electrode, a gate dielectric and an interfacial layer. The electrostatic potential at an interface between the gate electrode and the gate dielectric of a MOSFET device can be controlled by introducing one or more interfacial layer(s) of a dielectric material, at the monolayer(s) level (i.e., preferably two monolayers), between the gate electrode and the gate dielectric. A method for its manufacture is also provided and its applications.
