摘要:
A semiconductor device includes an emitter layer: a base layer; and a collector layer, wherein the collector layer and the emitter layer each include a heavily doped thin sublayer having a high impurity concentration, and each of the heavily doped thin sublayers has an impurity concentration higher than those of semiconductor layers adjacent to each heavily doped thin sublayer.
