Abstract

The semiconductor device comprises a silicon substrate, a boron-doped high resistant silicon carbide layer that is formed on the silicon substrate and a silicon carbide layer formed on the high resistant silicon carbide layer. The silicon carbide layer that is formed on the high resistant silicon carbide layer provides an electrical insulation for the device so that improved device characteristics are obtained.
