摘要:
A surface channel transistor is provided in a semiconductive device. The surface channel transistor is either a PMOS or an NMOS device. Epitaxial layers are disposed above the surface channel transistor to cause an increased bandgap phenomenon nearer the surface of the device. A process of forming the surface channel transistor includes grading the epitaxial layers.

Embodiments of an apparatus and methods for providing three-dimensional complementary metal oxide semiconductor devices comprising modulation doped transistors are generally described herein. Other embodiments may be described and claimed, which may include a modulation doped heterostructure, wherein the modulation doped heterostructure may comprise an active portion having a first bandgap and a delta doped portion having a second bandgap.
摘要:
Embodiments described include straining transistor quantum well (QW) channel regions with metal source/drains, and conformal regrowth source/drains to impart a uni-axial strain in a MOS channel region. Removed portions of a channel layer may be filled with a junction material having a lattice spacing different than that of the channel material to causes a uni-axial strain in the channel, in addition to a bi-axial strain caused in the channel layer by a top barrier layer and a bottom buffer layer of the quantum well.

A quantum well (QW) layer is provided in a semiconductive device. The QW layer is provided with a beryllium-doped halo layer in a barrier structure below the QW layer. The semiconductive device includes InGaAs bottom and top barrier layers respectively below and above the QW layer. The semiconductive device also includes a high-k gate dielectric layer that sits on the InP spacer first layer in a gate recess. A process of forming the QW layer includes using an off-cut semiconductive substrate.
