Abstract
A technique is provided for protecting an interlayer insulating film formed of an organic low dielectric constant material from any damage applied in a semiconductor process, and for attaining the decrease leak current in the interlayer insulating film, resulting in the improvement of reliability of a semiconductor device. The semiconductor device according to the present invention has an organic insulating films having openings. The organic insulating films have modified portions facing the openings. The modified portions contains fluorine atoms and nitrogen atoms. The concentration of the fluorine atoms in the modified portions is lower than the concentration of the nitrogen atoms. The above-mentioned modified layers protect the semiconductor device from the damage applied in the semiconductor process, while suppressing the corrosion of the conductors embedded in the openings.
