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

Abstract

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.
