Abstract
A voltage booster transistor with an optimal conducting path formed in widebandgap semiconductors like Silicon Carbide and Diamond, is provided as a power transistor with a voltage rating >200V. Contrary to conventional vertical design of power transistors, a higher, optimum doping for a given thickness supports higher Source/Drain blocking voltage. A topside and backside gate region of the opposite conductivity type than the channel region providing control of source to drain current path through a small gate voltage. The backside gate and the Drain junction are able to support the rated blocking voltage of the device.
