    摘要: The present disclosure describes a method and apparatus for implementing a 3D (three dimensional) strained high mobility quantum well structure, and a 3D strained surface channel structure through a Ge confinement method. One exemplary apparatus may include a first graded SiGe fin on a Si substrate. The first graded SiGe fin may have a maximum Ge concentration greater than about 60%. A Ge quantum well may be on the first graded SiGe fin and a SiGe quantum well upper barrier layer may be on the Ge quantum well. The exemplary apparatus may further include a second graded SiGe fin on the Si substrate. The second graded SiGe fin may have a maximum Ge concentration less than about 40%. A Si active channel layer may be on the second graded SiGe fin. Other high mobility materials such as III-V semiconductors may be used as the active channel materials. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.

    摘要: A nonplanar semiconductor device and its method of fabrication is described. The nonplanar semiconductor device includes a semiconductor body having a top surface opposite a bottom surface formed above an insulating substrate wherein the semiconductor body has a pair laterally opposite sidewalls. A gate dielectric is formed on the top surface of the semiconductor body on the laterally opposite sidewalls of the semiconductor body and on at least a portion of the bottom surface of semiconductor body. A gate electrode is formed on the gate dielectric, on the top surface of the semiconductor body and adjacent to the gate dielectric on the laterally opposite sidewalls of semiconductor body and beneath the gate dielectric on the bottom surface of the semiconductor body. A pair source/drain regions are formed in the semiconductor body on opposite sides of the gate electrode.

    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 is claimed. 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 then formed in the semiconductor body on opposite sides of the gate electrode.

A gate electrode is formed on the gate dielectric on the top surface of the semiconductor body and is formed adjacent to the gate dielectric on the laterally opposite sidewalls of the semiconductor body. A thin film is then formed adjacent to the semiconductor body wherein the thin film produces a stress in the semiconductor body.
