Thin
sapphire crystal wafers were the first successful use of an insulating substrate
upon which to deposit silicon to make the integrated circuits known as silicon
on sapphire or "SOS"; now other substrates can also be used for the
class of circuits known more generally as silicon on insulator. Besides its
excellent electrical insulating properties, sapphire has high thermal
conductivity. CMOS chips on sapphire are especially useful for high-power
radio-frequency (RF) applications such as those found in cellular telephones, public-safety
band radios, and satellite communication systems. "SOS" also allows
for the monolithic integration of both digital and analog circuitry all on one
IC chip, and the construction of extremely low power circuits.
The main part for growing sapphire is
tungsten crucible, which can be customized.
