e/Float-zone silicon

Information
has gloss	eng: Float-zone silicon is a high-purity alternative to silicon grown by the Czochralski process. The concentrations of light impurities, such as carbon and oxygen, are extremely low. Another light impurity, nitrogen, helps to control microdefects and also brings about an improvement in mechanical strength of the wafers, and is now being intentionally added during the growth stages.
