Patent ID: 7342292

Claim:
A capacitor assembly, comprising: a substrate; a first conductive auxiliary layer on the substrate; a capacitor dielectric, which is connected to the first conductive auxiliary layer within a first boundary area between the capacitor dielectric and the first conductive auxiliary layer; a second conductive auxiliary layer which is connected to the capacitor dielectric within a second boundary area between the capacitor dielectric and the second conductive auxiliary layer, wherein an effective capacitor area is present where the first boundary area and the second boundary area overlap the dielectric; and a contact electrode for contacting the first conductive auxiliary layer in a contacting area, wherein the contacting area is disposed on a surface of the first conductive auxiliary layer opposing the first boundary area and overlaps with the effective capacitor area only partly or not at all, so that at least part of the first conductive auxiliary layer, which is within the effective capacitor area, is adjacent to the substrate or not adjacent to the contact electrode; wherein the contact electrode encircles or encloses in rectangular shape the effective capacitor area.
