Abstract:
1. A method of manufacturing a semiconductor device in which an insulating film is formed on a substrate, said method comprising the steps of: (a) forming a low-pressure insulating film on the substrate, by converting a film-forming gas at a first gas pressure into a plasma and contacting the substrate with the plasma; and (b) forming a high-pressure insulating film on said low-pressure insulating film, by converting said film-forming gas at a second gas pressure higher than the first gas pressure into a plasma and contacting said low-pressure insulating film with the plasma of said film-forming gas at the higher pressure; and wherein said first gas pressure is in the range of 0.1 Torr to 1 Torr, and said second gas pressure is in the range of 1 Torr to 10 Torr.
