So far, Si BJT performance has been the main barrier for silicon to penetrate wireless RF front-ends. While SiGe HBTs have removed the barrier, RF isolation and system cost issues still remain. Since silicon substrates are conductive, it is not practical to build high-quality passive elements on-chip. However, much of the cost in current RF systems using discrete components comes from the passive elements. 5, now gives the RF designers a rich environment to realize applications for the wireless marketplace.
6. OPTOELECTRONIC DEVICES The optoelectronics realm has traditionally been reserved to III–V and II–VI compound semiconductors, due to the availability of direct transitions and heterostructures. However, the introduction of SiGe allows heterostructures to be fabricated in traditional Si-only technologies, which expands the potential of Si optoelectronics. 10. 10. The integrated silicon chip of the future: CMOS, HBT/bipolar, SiGe quantum devices, SiGe detectors, SiGe waveguides and light emitter all on a chip.
Zero net strain). 3), for about 12% Ge in Si and 1% C in silicon, the mismatch is equal and opposite and a strain symmetrized structure with average zero strain may be obtained. Addition of substitutional carbon to the Si1−x Gex material system can provide an additional design parameter in band structure engineering on Si substrates. 66 eV (Ge) exist, the Si1−x−y Gex Cy system may result in an increase in the bandgap to values greater than those of SiGe and Si, in addition to other interesting properties such as the highest known thermal conductivity (diamond), high hole mobility (Ge) and matured processing technology (Si).
