Silicon-germanium devices including MOSFETs, photogates and photodiodes, are produced by implanting the Si or polycrystalline silicon substrate with Ge , to realize active SiGe regions within Si which are substantially free from defects, at an appropriate point in
Silicon-germanium (SiGe) is beginning to replace gallium arsenide (GaAs) in wireless communications devices. SiGe chips, with high-speed properties, can be made with low-cost, well-established production techniques of the silicon-
The development of the Germanium transistor opened the door to countless applications of solid state electronics. From 1950 through the early 1970s, this area provided an increasing market for germanium, but then high purity silicon began replacing Germanium in transistors, diodes, and rectifiers.
