Title: Manufacture of bipolar transistor
Inventor: DEGUCHI TATSUYA
IPC: H01L29/72
Filed: 1987-02-19
Abstract: PURPOSE:To prevent leakage of current and to improve the yield and reliability of a transistor, by performing heat treatment for diffusing dopants with different conductivity types into an active region of a transistor so as to form a base region having one conductivity type and an emitter region having the other conductivity type. CONSTITUTION:On a semiconductor substrate 1, there are provided a polycrystalline silicon layer 3A having one conductivity type and a polycrystalline silicon layer 3B having the other conductivity type successively. The substrate is heat treated so that the dopants of the different conductivity types contained in these layers are diffused into an active region of a transistor which is provided by the semiconductor substrate 1. By using the polycrystalline silicon layers 3A and 3B doped with different dopants, it becomes possible to decrease the widths of distribution of the respective diffusion sources while increasing the distance between the different diffusion sources and, therefore, the emitter-base junction is enabled to be formed within the substrate. Thereby, the leakage of current is prevented and the yield as well as reliability can be improved.
