Silicon is one of the most abundant solid elements on planet earth. In fact, the earth’s crust is 25% silicon. Despite this, virtually all of this element exists as compounds. Silicon is rarely found in elemental form. As a result, in order to obtain the monocrystalline silicon that is necessary to build silicon wafers, silicon needs to be produced. One of the most popular growth techniques that are used to produce silicon for wafers is the float zone (FZ) technique. The silicon that is produced by this technique is used to create float zone wafers. Do you want to learn more about float zone wafers? Then keep reading for some super interesting facts.

5 Interesting Facts About Float Zone Wafers

Fact #1:
The float zone process was developed at Bell Labs by Henry Theuerer in 1952.
Fact #2:
Float zone silicon is the highly pure alternative to silicon crystals grown by the Czochralski process.
Fact #3:
Float zone wafers are commonly used to manufacture discrete power devices, high-efficiency solar products, RF chips, and optical products.
Fact #4:
The purity of float zone silicon allows it to go through a lighter doping process, which sometimes produces resistivity measurements of up to 50,00 ohm-com.
Fact #5:
The concentrations of light impurities, such as oxygen and carbon, are extremely low in float zone silicon wafers.
