What are Float Zone Silicon Wafers Used For?

Float-zone (FZ) silicon wafers also called undoped or intrinsic are used in applications that require purity that is much higher than Czochralski (CZ) grown silicon.

Examples include:

  • Power devices & detectors
  • Highly transparent to terahertz radiationcy, so it's used to fabricate optical components - lenses and windows
  • Satellite solar arrays

We have a large selection in stock, but we can customize any order in small and large quantities.

When researchers need the higher purity Silicon, they use FZ Silicon substrates instead of  Czochralski grown silicon.

Or simply put, Float Zone Si is most ly used low volume applications that require high-efficiency while CZ Silicon is used for high volume, less expensive applications.

Below are just some of the Float Zone wafers that we have in stock.
