ABSTRACT:
Termination of a high voltage device is achieved by a plurality of discrete deposits of charge that are deposited in varying volumes and/or spacing laterally along a termination region. The manner in which the volumes and/or spacing varies also varies between different layers of a multiple layer device. In a preferred embodiment, the variations are such that the field strength is substantially constant along any horizontal or vertical cross section of the termination region.
