Patent ID: 8642400

Claim:
A method of manufacturing a semiconductor device, comprising: forming a first metal film on an insulating film over a semiconductor substrate; forming a capacitor lower electrode by patterning the first metal film; forming a dielectric film on an upper surface and side surfaces of the capacitor lower electrode and on the insulating film; forming a conductive protection film on the dielectric film; patterning the conductive protection film into a shape of covering the capacitor lower electrode; forming a capacitor dielectric film in a shape of covering the upper surface and the side surfaces of the capacitor lower electrode, by patterning the dielectric film so that the patterned conductive protection film covers an upper surface of the capacitor dielectric film; forming a second metal film on the patterned conductive protection film and the insulating film; forming a capacitor upper electrode that covers at least an upper surface of the patterned conductive protection film, by patterning the second metal film; and forming a wiring on the insulating film by patterning the second metal film.
