Overview
Single-crystal diamond wafers enable critical advances in both RF power technology used for 5G communications and satellites; as well as in the power electronics used in electric vehicles.
CVD stands for “Chemical Vapor Deposition,” the process of breaking down natural gas like methane into carbon atoms that amass around a diamond starter to form a new diamond. The processing occurs in a vacuum chamber where crystals undergo heat and pressure treatment to eliminate coloration.
