Zusammenfassung:PROBLEM TO BE SOLVED: To provide the manufacturing method of a semiconductor device, which can form a barrier insulating film, having sufficient performance for preventing the diffusion of copper and can form a main insulating film having a sufficiently low dielectric constant, while improving the throughput, when the barrier insulating film and the main insulation film on it are sequentially formed on wiring which is mainly constituted of a copper film. SOLUTION: The method has a process for applying electric power, having a first frequency f1 to first film-forming gas containing at least silicon-containing gas silicon and gas containing oxygen, making first film-forming gas into plasma, making them to react each other and forming the barrier insulating film 35a on a substrate 21, where the film is formed and a process for applying a second frequency f2 which is higher than the first frequency f1 to second film-forming gas containing at least gas containing silicon and a gas oxygen- containing, making second film-forming gas into a plasma, making them react with each other and forming the main insulation film 35a having a low dielectric constant on the barrier insulating film 35a.
