Patent ID: 8431978

Claim:
A semiconductor device comprising: (a) a semiconductor device; (b) an element isolation region formed over the semiconductor substrate; and (c) a first capacitor element and a second capacitor element disposed spacedly from each other over the element isolation region, the first capacitor element including: (c1) a first lower electrode formed over the element isolation region; (c2) a capacitor insulating film formed over the first lower electrode; and (c3) an upper electrode formed over the capacitor insulating film, the second capacitor element including: (c4) a second lower electrode formed over the element isolation region; (c5) the capacitor insulating film formed over the second lower electrode; and (c6) the upper electrode formed over the capacitor insulating film, wherein the first capacitor element and the second capacitor element have the capacitor insulating film and the upper electrode in common, wherein the length of the upper electrode in a first direction is larger than the sum of the length of the first lower electrode in the first direction and the length of the second lower electrode in the first direction, the length of the upper electrode in a second direction intersecting the first direction is smaller than each of the length of the first lower electrode in the second direction and the length of the second lower electrode in the second direction, wherein the first capacitor element is formed in a region where the upper electrode and the first lower electrode overlap each other planarly, the second capacitor element is formed in a region where the upper electrode and the second lower electrode overlap each other planarly, wherein over a surface of the upper 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 upper electrode in the second direction and a region spaced apart from a stepped region of the upper electrode in the first direction.
