ABSTRACT:
A bipolar transistor includes: a first semiconductor layer having an intrinsic base region and an extrinsic base region; and a second semiconductor layer having a portion located on the intrinsic base region to be an emitter region or a collector region. A capacitive film is provided on the extrinsic base region using the same semiconductor material as that for the second semiconductor layer. A base electrode is formed on the first semiconductor layer to cover the capacitive film and the extrinsic base region.
