Abstract
Disclosed is a semiconductor device in which emitter pad electrodes connected to an active region, collector and base pad electrodes are formed on a surface of a semiconductor substrate. Furthermore, on a back surface of the semiconductor substrate, a backside electrode is formed. Moreover, the emitter pad electrodes connected to a grounding potential are connected to the backside electrode through feedthrough electrodes penetrating the semiconductor substrate in a thickness direction.
