    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.

    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 method is described for forming an element of a microelectronic circuit. A sacrificial layer is formed on an upper surface of a support layer. The sacrificial layer is extremely thin and uniform. A height-defining layer is then formed on the sacrificial layer, whereafter the sacrificial layer is etched away so that a well-defined gap is left between an upper surface of the support layer and a lower surface of the height-defining layer. A monocrystalline semiconductor material is then selectively grown from a nucleation silicon site through the gap. The monocrystalline semiconductor material forms a monocrystalline layer having a thickness corresponding to the thickness of the original sacrificial layer.
