Most commonly used in MEMS and advanced CMOS integrated circuit fabrication, SOI wafers provide a manufacturing solution which helps reduce power and heat while increasing the speed performance of a device. SOI wafers are a three layer material stack composed of the following: Active layer of prime quality silicon (DEVICE LAYER) over a buried layer(BOX) of electrically insulating silicon dioxide, over a bulk silicon support wafer (HANDLE). SOI wafers are unique products which are custom built for specific end-user applications. SVM offers two types of SOI: Thick Film and Thin Film.
