Abstract:
A semiconductor device comprising:a capacitor electrode formed on a semiconductor substrate, and having an upper surface; an insulating film formed on and in contact with said capacitor electrode, and having a wiring trench and an upper surface, wherein a bottom portion of said wiring trench directly exposes the upper surface of said capacitor electrode; a wiring layer filled in inside said wiring trench, and having an upper surface and a lower surface, wherein the upper surface of said wiring layer is located on approximately the same plane as the upper surface of said insulating film and the lower surface of said wiring layer is in direct contact with said capacitor electrode; a conductive region located below said insulating film, wherein a contact hole which reaches to said conductive region, and another trench, which is connected to said contact hole, are formed in said insulating film; and another wiring layer which is filled in inside of said other trench and said contact hole.
