Silicon on insulator (SOI) technology refers to the use of a layered silicon-insulator-silicon substrate in place of conventional silicon substrates in semiconductor manufacturing, especially microelectronics, to reduce parasitic device capacitance, thereby improving performance. SOI-based devices differ from conventional silicon-built devices in ...

or SOI pressure sensing technology enables sensing diaphragms to be used at much higher temperatures. Unlike ion implanted silicon strain gauge diaphragms SOI does not have P-N junctions that begin to breakdown at high temperatures producing leakage currents which cause unstable performance.
