| 摘要 |
According to the present invention, there is provided a semiconductor device fabrication method having: coating a semiconductor substrate with a silazane perhydride polymer solution prepared by dispersing a silazane perhydride polymer in a solvent containing carbon, thereby forming a coating film; forming a polysilazane film by volatilizing the solvent by heat-treating the coating film; and inserting the semiconductor substrate into a predetermined furnace, lowering a pressure in the furnace, and oxidizing the polysilazane film while the pressure in the furnace is raised by supplying steam into the furnace, thereby forming a silicon oxide film.
