    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.
