Patent ID: 8258561

Claim:
A semiconductor device comprising: (a) a semiconductor device; (b) a first capacitor element formed over the semiconductor substrate; and (c) a second capacitor element formed over the first capacitor element, the first capacitor element including: (b1) a first electrode comprising the semiconductor substrate; (b2) a first capacitor insulating film formed over the first electrode; and (b3) a second electrode formed over the first capacitor insulating film, the second capacitor element including: (c1) the second electrode; (c2) a second capacitor insulating film formed over the second electrode; and (c3) a third electrode formed over the second capacitor insulating film, wherein the length of the third electrode in a first direction is larger than that of the second electrode in the first direction, the length of the third electrode in a second direction intersecting the first direction is smaller than the length of the second electrode in the second direction, wherein the first capacitor element is formed in a region where the semiconductor substrate and the second electrode overlap each other planarly, the second capacitor element is formed in a region where he second electrode and the third electrode overlap each other planarly, wherein over a surface of the third electrode, there exist a region where a metal silicide film is formed, and a region where the metal silicide film is not formed, and wherein the metal silicide film-formed region comprises a region spaced apart from an end region of the third electrode in the second direction and a region spaced apart from a stepped region of the third electrode in the first direction.
