Abstract
A transcalent semiconductor device comprises a body of semiconductor material having first and second major opposed surfaces. The first surface includes at least one region of first type conductivity and a region of opposite type conductivity. A first heat pipe having a conductive contact disc is in electrical and thermal contact with substantially all of the first surface. The conductive contact disc has an aperture therein. A control electrode for initiating conduction through the semiconductor material extends through the aperture in the disc and contacts the region of opposite type conductivity. A second heat pipe is disposed in electrical and thermal conductive relationship with the second surface. In an alternative embodiment, a fiber optic light pipe controls the initiation of conduction through the semiconductor material by transmitting photons to the region of opposite type conductivity.
