Title: Hetero junction bipolar transistor and its manufacture
Inventor: ARAI KEITA
IPC: H01L29/165
Filed: 1991-12-24
Abstract: PURPOSE:To enable high speed operation, by applying a 3c-SiC layer whose energy band gap is wide to an emitter region and a collector region, and applying an Si crystal layer whose energy band gap is narrow to a base region. CONSTITUTION:A 3c-SiC crystal layer of a first conductivity type, an Si crystal layer of a second conductivity type, and a 3c-SiC crystal layer of a first conductivity type are formed step-wise. The two 3c-SiC crystal layers are formed as a collector region 4 and an emitter region 5, respectively. The Si crystal layer is formed as a base region 6. Since the band gap of the 3c-SiC crystal layers forming the emitter region 4 and the collector region 5 is wider than that of the Si crystal layer forming the base region 6, the emitter injection efficiency is improved. Since the band gap of the collector region 4 also is wide, the positive hole injection from the base region 6 to the collector region can be blocked, so that the base region 6 is formed as a high concentration region and its resistance is reduced. Thereby high speed operation is realized.
