ABSTRACT:
A semiconductor device is disclosed which uses the phenomenon of "scattering limited velocity effect" for practical current limiting purposes. A monolithic chip of semiconductor material has a plurality of active spot regions or conduction channels formed by an encompassing inactive region which surrounds and separates each of the channels. The inactive region blocks current flow and performs a heat sinking function, the latter being necessary because of the high power density within the conduction channels at which the "scattering limited velocity effect" is exhibited.
