The Float Zone (FZ) Method produces a highly pure form of silicon. The purity of the material allows for lower defect concentrations and higher resistivity levels and it is useful in high-power devices, detectors and solar applications. SQI offers the very best Float Zone material commercially available, not made from CZ re-melts but from high-quality polysilicon, thus allowing for resistivity’s in excess of 10k ohm –cm. Silicon Quest is the exclusive representative for Topsil Float Zone Products in the USA. |
