  • High resistivity silicon carbide single crystal
    Patent number: 7018597
    Abstract: The purpose of the invention is to provide a high resistivity silicon carbide substrate with electrical properties and structural quality suitable for subsequent device manufacturing, such as for example high frequency devices, so that the devices can exhibit stable and linear characteristics and to provide a high resistivity silicon carbide substrate having a low density of structural defects and a substantially controlled uniform radial distribution of its resistivity.
    Type: Grant
