摘要:
Disclosed is a method of fabricating a semiconductor device, in which an interlayer insulating film having a low dielectric constant is formed by coating a wiring, and either a via hole or a contact hole is formed in the interlayer insulating film. The method of fabricating a semiconductor device having the interlayer insulating film 25 formed on the film-formed substrate 21 with the exposed wiring 23, comprises the step of converting a silicon compound containing only the Si, O, C and H into a plasma gas as a film-forming gas to react the plasma gas, thus forming the block insulating film 24 containing silicon (Si), oxygen (O), carbon (C) and hydrogen (H) between the wiring 23 and the interlayer insulating film 25.

The present invention relates to a semiconductor device in which an interlayer insulating film having a low dielectric constant is formed by covering wiring primarily made of a copper film, and to a method of manufacturing the same. In manufacturing the semiconductor device an insulating film having a low dielectric constant is formed on a substrate by converting a film-forming gas into a plasma for reaction. The method includes forming a low-pressure insulating film on the substrate by coverting the film-forming gas at a first gas pressure into a plasma and forming a high-pressure insulating film on the low-pressure insulating film by converting the film-forming gas at second gas pressure, higher than the first gas pressure, into a plasma and reaction.
