What is Float Zone Silicon?

Discrete Power Device Float Zone
RF Microchip Float Zone
MOS Power Float Zone
High Efficiency Solar Cell 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.
