SEMICONDUCTOR CHIP WITH A BASE ELECTRODE AND AN EMITTER ELECTRODE EXPOSED ON ONE OF A PAIR OF OPPOSITE LATERAL FACES AND A COLLECTOR ELECTRODE EXPOSED ON A REMAINING ONE OF THE PAIR OF THE OPPOSITE LATERAL FACES

摘要

A semiconductor chip provided, at a lateral face thereof, with an electrode for external electric connection. Where a semiconductor chip has a plurality of electrodes, all the electrodes are preferably formed at one or more lateral faces of the semiconductor chip. Each electrode is preferably embedded in a groove which is formed in a lateral face of the semiconductor chip and which is opened laterally of the semiconductor chip. The semiconductor chip may be a discrete bipolar transistor element. In this case, each of the base electrode, the emitter electrode and the collector electrode is preferably formed at a lateral face of the semiconductor chip.
