After silicon wafers are loaded into a high temperature oxidation furnace, oxygen or water vapor reacts with silicon. The dry oxygen reaction is expressed as Si＋O₂→SiO₂; the wet oxygen reaction is written as Si＋2H₂O→SiO₂＋2H₂.
High-resistivity silicon (with resistivity above 1,000 Ω·cm) holds an irreplaceable position in RF MEMS devices. Thanks to its ultra-low net doping concentration (below \(10^{12}\ \mathrm{cm^{-3}}\)), it delivers extremely low RF substrate loss.
The four-point probe method is a common technique for measuring the resistivity and sheet resistance of semiconductor materials. Its basic principle involves placing four equally spaced probes on the sample surface. A constant current is applied through the two outer probes...
