Claim:
1. An integrated capacitor, comprising: a layer of dielectric material known as a functional dielectric material based on a crystallized material of perovskite type, between at least one first electrode known as a bottom electrode above a surface of a substrate and at least one second electrode known as a top electrode above the bottom electrode; an etched contacting layer having a first region over a surface of the top electrode, a second region that extends horizontally beyond a first edge of the top electrode, a third region over a surface of the bottom electrode, and a fourth region that extends horizontally beyond a second, opposing edge of the top electrode; a layer of electrically insulating material over the top electrode, the layer of electrically insulating material defining a first contact between the first region of the etched contacting layer and the surface of the top electrode and a third contact between the third region of the etched contacting layer and the surface of the bottom electrode; and a protective insulating layer over the etched contacting layer, the protective insulating layer being etched to define a second contact in the second region of the etched contacting layer entirely horizontally beyond the first edge of the top electrode and a fourth contact in the fourth region of the etched contacting later entirely horizontally beyond the second, opposing edge of the top electrode, wherein:
