Abstract:
A film forming method for forming a silicon-containing barrier insulating film on a substrate comprising the steps of:(a) preparing a film-forming gas comprising, (1) at least one member selected from the group consisting of siloxane compounds having Siâ€”H bonds and (2) at least one oxygen-containing gas selected from the group consisting of O2, N2O, NO2, CO, CO2, and H2O; (b) converting the film-forming gas into a plasma; (c) contacting the substrate with the plasma to form the silicon-containing barrier insulating film on the substrate; and (d) forming a porous insulating film by plasma enhanced CVD or forming a SiOF film, as an interlayer insulating film, directly on said barrier insulating film.
