Title: Heterojunction bipolar transistor and its manufacture
Inventor: FUJII SATORU
IPC: H01L21/331
Filed: 1992-05-27
Abstract: PURPOSE:To suppress difusion of doped impurities by doping the impurity to become an acceptor within a base layer and that occupying the same site and becoming a donor in the same layer or an adjacent later. CONSTITUTION:Si which will act as a donor is ion-imflanted in the region of a collector layer 3 excluding the central part. A base layer 4 of p<+>-AlGaAs doped with Be which occupies the same site as the ion-implanted Si layer and becomes an acceptor is formed on top of it. By ion implantation of Si, atomic holes VGu10 are introduced in the collector layer. The atomic holes VGu10 and the interstitial atoms IGu11 of the base layer 4 disappear by annealing, thus the difusion of Be within the base layer 4 is prevented. In this way, the interstitial atoms in the base layer or the atomic holes can be eliminated.
