Float Zone (FZ) silicon is commonly used in the manufacture of discrete power devices, high efficiency solar, RF chips and optical products. FZ silicon is a high purity alternative to Czochalski (CZ) grown silicon whereas the concentration of carbon and oxygen impurities are extremely low. The purity of FZ allows the silicon to go through a lighter doping process, sometimes producing resistivity measurements reaching heights of up to 50,000 ohm-cm.

SVM offers FZ wafers ranging in diameter from 50mm to 200mm. Intrinsic wafers are available. Below please find examples of SVM standard FZ wafer specifications.
