Abstract:
1. A semiconductor device comprising: a semiconductor substrate; an interlayer insulating film formed on said semiconductor substrate; a contact hole passing through said interlayer insulating film to reach a surface of said semiconductor substrate; a conductive plug formed in said contact hole and connected to said surface of said semiconductor substrate; a conductive film formed in said contact hole so as to be adhered to a top face of said conductive plug; a first capacitor electrode connected to said conductive film; a capacitor dielectric film being in contact with said first capacitor electrode; and a second capacitor electrode, said capacitor dielectric film being interposed between said first and second capacitor electrodes, to form a capacitor, wherein said conductive film is made of a material identical to that of said first capacitor electrode, and said first capacitor electrode is connected to said conductive film so as not to completely cover a surface of said conductive film exposed in said contact hole and to dig into said conductive film.
