Title: Formation of multilayer insulating film
Inventor: NIWA HITOSHI
IPC: H01L29/788
Filed: 1989-06-02
Abstract: PURPOSE:To enhance a film-thickness uniformity and a film quality by using an RTO film instead of a thermal oxide film of polysilicon of a multilayer insulating film. CONSTITUTION:A silicon oxide film(RTO film) 4 is formed on a silicon substrate 1 or a polysilicon electrode by a rapid lamp thermal oxidation(RTO) method; then, a CVD silicon nitride film 5 is deposited on the RTO film 4 by a chemical vapor growth(CVD) method. Then, this CVD silicon nitride film 5 is thermally oxidized; a thermal-oxidation silicon nitride film 6 is formed on the surface of the film. Since the RTO film 4 is formed by a high-temperature and short- time heat treatment method, it is not so influenced by a concentration of phosphorus impurities as a thermal oxidation operation by using an ordinary oxidation furnace. In addition, the RTO film 4 can be formed in a time which is extremely shorter than a thermal oxidation time of polysilicon in the ordinary oxidation furnace; the silicon oxide film 4 is of the same film thickness of that formed in the ordinary oxidation furnace. Thereby, a film-thickness uniformity over the face is good; it is possible to prevent a film quality of a thin gate insulating film from being deteriorated.
