Abstract
A semiconductor device and a method for manufacturing the semiconductor device are provided. The method includes forming a collector region of a second conductivity type in a semiconductor substrate of a first conductivity type; forming a base region of the first conductivity type in the collector region, and forming an emitter region of the second conductivity type into the base region; forming an emitter in the emitter region, and forming a collector in the collector region; and forming a base in the semiconductor substrate through implanting high concentration impurity ions of the first conductive type into the semiconductor substrate.
