Popis: | Three advanced architectures for ultimate progress in Ge p-Metal Oxide Semiconductor Field Effect Transistors are discussed in this paper. Different routes for stress implementations in Ge channels, either biaxial or uniaxial, are proposed by advanced selective Chemical Vapor Deposition techniques. Selective SiGe Strained Relaxed Buffer growth in Shallow Trench Isolation is first discussed to implement biaxial compressive strained Ge Quantum Wells on top of it. Next, innovative GeSn chemical vapor deposition technique is described in order to build either uniaxial strained Ge channel with GeSn Source/Drain stressors or compressively biaxial strained GeSn Quantum Well channels on Ge buffer layers. |
