Growth of silicon carbide epitaxial layers on 150-mm …
15/10/2013· Epitaxial layers on a 150-mm-diameter silicon carbide wafer have been grown using a horizontal hot-wall chemical vapor deposition system for three 150-mm-diameter wafers. We investigated the surface morphology and surface defects such as shallow pits and triangular defects of the grown epitaxial layers, as well as the thickness and carrier concentration uniformities.
