    摘要: A method for fabricating a semiconductor device includes the steps of forming an insulating film on a semiconductor substrate, forming a plurality of wiring trenches in the insulating film, forming a plurality of wirings in the plurality of wiring trenches, forming a resist mask having an opening for selectively exposing one of regions between the plurality of wirings, on the insulating film and the plurality of wirings, forming an air gap trench by removing the insulating film from the selectively exposed one of the regions between the plurality of wirings by etching using the resist mask, and forming an air gap in the air gap trench by depositing an inter-layer insulating film over the plurality of wirings after removal of the resist mask.

    摘要: A first insulating film is formed on a semiconductor substrate, an interconnect groove is formed in the first insulating film, the inside of the interconnect groove is filled with a metal film, thereby forming a first interconnect. Then, a protective film is formed on the first insulating film and the first interconnect, and the surface of the protective film is exposed to reactive gas, thereby forming a reaction layer on an interface between the first interconnect and the protective film.
