Silicon-germanium - Wikipedia

SiGe , or silicon-germanium, is an alloy with any molar ratio of silicon and germanium, i.e. with a molecular formula of the form Si1−xGex. It is commonly used as a semiconductor material in integrated circuits (ICs) for heterojunction bipolar transistors or as a strain-inducing layer for CMOS transistors. IBM introduced the technology into mainstream manufacturing in 1989. This relatively new technology offers opportunities in mixed-signal circuit and analog circuit IC design and manufacture. SiGe is also used as a thermoelectricUS6977400B2 - Silicon germanium CMOS channel,A method for fabricating a semiconducting device on a substrate, where the improvement includes forming a strained silicon germanium channel layer on the substrate.
