Patent ID: 7420237

Claim:
A capacitor element comprising: an interlayer insulating film formed over a substrate; a first hydrogen barrier film formed on the interlayer insulating film, wherein a hole is formed in the interlayer insulating film and the first hydrogen barrier film; a capacitor element comprising a lower electrode, a capacitor dielectric film of a ferroelectric material or a high dielectric material and an upper electrode, each of which being formed in a region extending from within the hole toward a position above the first hydrogen barrier film; and a second hydrogen barrier film formed over the capacitor element and the first hydrogen barrier film, wherein the second hydrogen barrier film is in contact with the first hydrogen barrier film in a periphery of the capacitor element, while covering the entire top surface of the capacitor element; wherein the first hydrogen barrier film is formed of an insulating material different from that of the interlayer insulating film; and wherein an edge portion of the capacitor dielectric film is in contact with the first hydrogen barrier film.
