In the production of silicon wafers, there are several techniques used to modify the characteristics and behaviors of the silicon wafers in order to change the properties and uses of the wafer. Float zone wafers are one of the different types of modifications that can be made to a silicon wafer depending on the project or purpose of the silicon wafer. What is a float zone wafer and what are they used for? Find out more throughout this blog!

What is a Float Zone Wafer?

High quality float zone wafers are available from Wafer World

A float zone wafer is a product of a wafer created through the float zone method. Similar to the Czochralski method (CZ), float zone is a method to grow the silicon crystals. It’s based on a principle that was invented in 1962, founded on the zone-melting principle. Through a partial melting and necking process a single and purified crystal is formed. The purity of this method allows the silicon to go through a doping process that is somewhat lighter. The resistivity of a wafer that was formed with this method can also reach very high levels.

What are Float Zone Wafers Used for?

These types of silicon wafers are generally used for power devices and detector applications. High efficiency solar products and RF chips are also a common application for float zone wafers. These wafers also have a lot of optical applications, typically used to manufacture lenses and windows for terahertz applications.No matter what the use is for your float zone wafer, know that Wafer World can deliver the highest quality silicon wafer product.
