Title: Low temperature activating method for oxygen-doped polycrystalline silicon film
Inventor: YAMADA KOUICHIROU
IPC: H01L21/324
Filed: 1982-07-26
Abstract: PURPOSE:To sufficiently reduce the resistivity of an oxygen-doped polycrystalline silicon film by heat-treating in advance the film at a high temperature and then doping an impurity element, thereby reducing the diffusion of an impurity. CONSTITUTION:A P type base region 33 and an oxidized film 34 are formed on a single crystal substrate which has an N type low impurity density collector layer on an N type high impurity density collector layer 31. Then, an oxygen- doped polycrystalline silicon film 35 is accumulated by gas phase growth. After the heat treatment at high temperature, phosphorus is doped by an ion implantation method. Subsequently, a heat treatment is again performed at the temperature lower than the heat-treating temperature before doping the phosphorus. As a result, the diffusion of phosphorus from oxygen-doped polycrystalline silicon to single crystal silicon is reduced, and the boundary 36 can be regarded as an emitter and base junction. Aluminum electrodes 37a-37c are eventually deposited.
