Abstract
According to one embodiment, a collector electrode including metal is used for a sink region for connecting an n+ type buried layer, so that the sink region can be narrowly formed. Further, an interval between a base region and the collector electrode can be reduced, thereby considerably decreasing the size of the transistor. Furthermore, collector resistance is reduced, so that the performance of the transistor can be improved.
