Patent number: 10236369Abstract: Techniques are disclosed for forming a non-planar germanium quantum well structure. In particular, the quantum well structure can be implemented with group IV or III-V semiconductor materials and includes a germanium fin structure. In one example case, a non-planar quantum well device is provided, which includes a quantum well structure having a substrate (e.g. SiGe or GaAs buffer on silicon), a IV or III-V material barrier layer (e.g., SiGe or GaAs or AlGaAs), a doping layer (e.g., delta/modulation doped), and an undoped germanium quantum well layer. An undoped germanium fin structure is formed in the quantum well structure, and a top barrier layer deposited over the fin structure. A gate metal can be deposited across the fin structure. Drain/source regions can be formed at respective ends of the fin structure.Type: GrantFiled: October 23, 2017Date of Patent: March 19, 2019Assignee: INTEL CORPORATIONInventors: Ravi Pillarisetty, Jack T. Kavalieros, Willy Rachmady, Uday Shah, Benjamin Chu-Kung, Marko Radosavljevic, Niloy Mukherjee, Gilbert Dewey, Been Y. Jin, Robert S. Chau

Publication number: 20090075445Abstract: A transistor may be formed of different layers of silicon germanium, a lowest layer having a graded germanium concentration and upper layers having constant germanium concentrations such that the lowest layer is of the form Si1-xGex. The highest layer may be of the form Si1-yGey on the PMOS side. A source and drain may be formed of epitaxial silicon germanium of the form Si1-zGez on the PMOS side. In some embodiments, x is greater than y and z is greater than x in the PMOS device. Thus, a PMOS device may be formed with both uniaxial compressive stress in the channel direction and in-plane biaxial compressive stress. This combination of stress may result in higher mobility and increased device performance in some cases.Type: ApplicationFiled: November 19, 2008Publication date: March 19, 2009Inventors: Jack Kavalieros, Justin K. Brask, Mark L. Doczy, Matthew V. Metz, Suman Datta, Brian S. Doyle, Robert S. Chau, Everett X. Wang, Philippe Matagne, Lucian Shifren, Been Y. Jin, Mark Stettler, Martin D. Giles
