Abstract:
A method of manufacturing a semiconductor device including a semiconductor substrate and a plurality of memory cells each having a capacitor formed with said semiconductor substrate, comprising the steps of:forming a deposition preventing film on an insulating film formed over said semiconductor substrate; forming a plurality of holes in said insulating film in such a manner as to penetrate through said deposition preventing film; forming a first conductor film by chemical vapor deposition on only an inner surface and a bottom surface of each of said holes in said insulating film by utilizing said deposition preventing film; forming a dielectric film on said first conductor film and on said deposition preventing film at a predetermined temperature, a material of said first conductor film being Ru, Pt or Ir that does not lose conduction even when exposed to said predetermined temperature for forming said dielectric film; and forming a second conductor film on said dielectric film; said first and second conductor films and said dielectric film together constituting said capacitors.
