Abstract:
1. A method for manufacturing a semiconductor device having a fluorinated insulating film, said method comprising the steps of: depositing a SiCN film on the fluorinated insulating film, wherein a density of nitrogen in the SiCN film decreases in accordance with a distance from an interface between the fluorinated insulating film and the SiCN film, and a percentage of Si—N bonds in a first region that is a region in the SiCN film and in a vicinity of the interface between the insulating film and the SiCN film is larger than a percentage of Si—N bonds in a second region that is a region other than the first region in the SiCN film, and a percentage of Si—C bonds in the second region is larger than a percentage of Si—C bonds in the first region.
