Abstract:
A method of fabricating a semiconductor device including a structure having a conductive material and an insulating film formed on the conductive material comprising:a step of forming a contact hole in the insulating film and exposing the conductive material at a bottom thereof;a step of forming a wiring material comprising aluminum or including aluminum as a major component which is brought into electrical contact with the conductive material at least at the bottom of the contact hole;a step of forming a film including an element selected from the group consisting of 12 through 15 group elements as a major component on a surface of the wiring material; anda step of fluidizing the wiring material by a heating treatment,wherein the heating treatment is carried out at a temperature of 400.degree. C. or lower in an atmosphere including hydrogen.
