Abstract:
A stacked capacitor comprising:a substrate having a main surface; an interlayer insulating film disposed on said substrate; a conductive plug extending through said interlayer insulating film and reaching said main surface of said substrate; a surface-covering insulating film covering both said interlayer insulating film and said conductive plug; a first conductive layer connected to said conductive plug, extending through and above said surface-covering insulating film, and configured to form a first electrode of said stacked capacitor; a dielectric film disposed so as to cover said surface-covering insulating film and a part of said first conductive layer extending above said surface-covering insulating film; and a second conductive layer disposed so as to cover said dielectric film and configured to form a second electrode of said stacked capacitor.
