Patent ID: 7968420

Claim:
A method of manufacturing a semiconductor device, comprising: (a) forming a first insulating film over a substrate; (b) forming a first groove and a second groove by selectively removing the first insulating film, the first groove having a first depth and the second groove having a second depth, the second depth being smaller than the first depth, a bottom surface of the second groove being a portion of the first insulating film; (c) infusing a first conductive liquid material into the first groove and a second conductive liquid material into the second groove; (d) treating the first conductive liquid material in the first groove and the second conductive liquid material in the second groove to form a first conductive film and a second conductive film, respectively; (e) forming a second insulating film over the first conductive film and the second conductive film; and (f) forming a third conductive film on the second insulating film, the second conductive film serving as a first electrode constituting a capacitor, and an area located above the second conductive film in the third conductive film serving as a second electrode constituting the capacitor.
