Abstract:
1. A method of manufacturing a semiconductor device, comprising: forming a conductive structure above a semiconductor substrate; forming an insulating film which covers the conductive structure; forming in the insulating film openings which expose part of a surface of the conductive structure; forming base films each constituted of a silicide material at a temperature of 350° C. or lower by one of a sputtering method and a CVD method so as to cover inner wall surfaces of the openings respectively; forming conductive plugs by filling up the openings with a conductive material via the base films, wherein the conductive structure has a noble metal layer in an upper layer part thereof, and wherein, to the noble metal layer, a material which contains at least one type selected from carbon monoxide chlorine compound, sulfur compound, phosphorous compound, and silicon compound is added.
