Preferred Float Zone Silicon Wafers

Float Zone-Preferred Float Zone(FZ-PFZ) silicon wafer has the lowest resistivity variations of the in-situ doped float zone products available. The dopant distribution is tightly controlled throughout the length of the monocrystalline rod.


Due to its purity it is well suited for lateral and vertical power devices like
Power MOSFET’s, IGBT’s and high power thyristors.
