Semiconductor Wafers

Silicon Wafer 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 that the silicon junction is above an electrical insulator.

SOI wafers are widely used in silicon photonics.The crystalline silicon layer on insulator can be used to fabricate optical waveguides and other passive optical devices for integrated optics.
