Filed: 1985-09-12
Abstract: PURPOSE:To obtain the film having excellent physical properties for a gate insulating film of a thin film transistor or an insulator protecting film of a semiconductor element by using nitrogen trifluoride gas as a nitrogen atom supply source. CONSTITUTION:Argon, hydrogen, monosilane, nitrogen trifluoride, disilane hexafluoride, silane tetrafluoride are disposed in gas cylinders 1 through valves 2, and suitably selected gases are fed to a mixture tank 3. The mixture gas mixed at the prescribed mixing ratio in the tank 3 is fed to a reaction vessel 7 while controlling the flow rate by a mass flow controller 6. An oil rotary pump 8 for exhaust the gas is attached to the vessel 7, and the exhaust gas is fed to a detriment removing system. When the nitrogen trifluoride containing no hydrogen is used as nitrogen atom supply source to be used for a TET gate insulating film, it can become a film which contains less content of hydrogen containing less N-H bond, ad contamination with ammonia can be eliminated.
