IPC: H01L31/10
Filed: 1992-08-21
Abstract: PURPOSE:To provide a phototransistor with proper breakdown voltage characteristics decided by the carrier density in a collector region without deteriorating the sensitivity to incident beams by a method wherein the diffusion of the impurities in the base region of the phototransistor into a collector region during the manufacturing process is suppressed. CONSTITUTION:Within a laminated structure of the photo-transistor, a thin film growing layer i.e., a diffusion stopper layer 5 comprising a mutual hetero- junction with a base region 3 and a collector region 6 is provided in a depletion layer region 4 of a base-collector junction formed by inverse bias. At this time, during the manufacturing process, the diffusion of the dopant added to the base region 3 traversing the depletion region 4 to the collector region 6 can be prevented by the diffusion stopper layer 5 thereby enabling the formation of a local high field region to be suppressed. In such a constitution, the diffusion stopper layer 5 is thinner so that the absorption characteristics-collector efficiency may be hardly affected.
