Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”

Epitaxy is a process in which an additional monocrystalline silicon layer is deposited on to the polished crystal surface of a silicon wafer. This process makes it possible to select the material properties independently of the polished substrate, and consequently to create wafers that have different properties in the substrate and the epitaxial layer.
Silicon epitaxy is widely used in semiconductor devices, primari-ly for its ability to grow lightly doped epitaxial layers over heavily doped substrates. A highly controlled epitaxial layer with an abrupt and controlled interface is required for high frequency, high
