What is Float Zone Silicon?

Float-zone silicon is the purest form of silicon. The ingot is made by vertical zone melting.

Float Zone (FZ) Silicon Wafers are used primarily for

• discrete power
• MOS Power
• high efficiency solar cells
• RF/Wireless chips
• or when very high resistivity is need increased performance.

Float Zone ingots are undoped, but can be intentionally doped by injecting gas dopants or using the Neutron Transmutation Doping (NTD) process.
