摘要:
A semiconductor device comprising a semiconductor body having a top surface and a first and second laterally opposite sidewalls as formed on an insulating substrate. A gate dielectric is formed on the top surface of the semiconductor body and on the first and second laterally opposite sidewalls of the semiconductor body. A gate electrode is then formed on the gate dielectric on the top surface of the semiconductor body and adjacent to the gate dielectric on the first and second laterally opposite sidewalls of the semiconductor body. The gate electrode comprises a metal film formed directly adjacent to the gate dielectric layer. A pair of source and drain regions are uniformed in the semiconductor body on opposite sides of the gate electrode.

摘要:
In a metal gate replacement process, strain may be selectively induced in the channels of NMOS and PMOS transistors. For example, a material having a higher coefficient of thermal expansion than the substrate may be used to form the gate electrodes of PMOS transistors. A material with a lower coefficient of thermal expansion than that of the substrate may be used to form the gate electrodes of NMOS transistors.

摘要:
Embodiments of the invention provide a device with a metal gate, a high-k gate dielectric layer and reduced oxidation of a substrate beneath the high-k gate dielectric layer. An oxygen barrier, or capping, layer on the high-k gate dielectric layer and metal gate may prevent such oxidation during processes such as spacer formation and annealing of ion implanted regions.
