Business Overview

Component Business

CVD SiC (Chemical Vapor Deposition Silicon Carbide) is a technology that deposits SiC using the chemical vapor deposition
method. Over the years, we have developed the capability to deposit from thin films to bulk forms of several millimeters,
securing a stable production process.
