| 摘要 |
The present invention relates to a semiconductor device manufacturing method for forming an interlayer insulating film having a low dielectric constant by coating a copper wiring. In configuration, in a semiconductor device manufacturing method of forming an insulating film 25 having a low dielectric constant on a substrate 21, the insulating film 25 is formed by plasmanizing a film forming gas containing any one oxygen-containing gas of N2O, H2O, and CO2, ammonia (NH3), and at least one of an alkyl compound having a siloxane bond and methylsilane (SiHn(CH3)4-n: n=0, 1, 2, 3) to react.
