Abstract
PURPOSE:To prevent the interaction of oxygen or nitrogen contained in silicon carbide with impurity in a base layer by a method wherein a high resistive region is interposed between silicon carbide and the base layer. CONSTITUTION:A silicon carbide 11 is not formed directly on a base layer 13 but isolated from the base layer 13 through the intermediary of a high resistive region 14. Thereby, oxygen or nitrogen contained in the silicon carbide 11 is made to be prevented from interacting with impurity doped in the base layer 13. Therefore, the impurity doped in the base layer 13 can be substatially increased in concentration, a re-coupling current at the interface between a base and an emitter is restrained from in creasing as well, a base current and an emitter current can be made to increase, and a base resistance can be made to be low, and thus a high speed operation can be realized.
