Abstract
A capacitor assembly has a substrate, a first conductive auxiliary layer on the substrate, a capacitor dielectric, a second conductive auxiliary layer and a contact electrode. Thereby the first conductive auxiliary layer is connected to the capacitor dielectric within a first boundary area and the second conductive auxiliary layer is connected to the capacitor dielectric within a second boundary area. Thereby, an effective capacitor area is present where the first boundary area and the second boundary area overlap across the capacitor dielectric. The contact electrode is connected to the first conductive auxiliary layer in a contacting area, wherein the contacting area is disposed on a surface of the first conductive auxiliary layer opposite to the first boundary area and overlaps the effective capacitor area partly or not at all, so that at least part of the first conductive auxiliary layer within the effective capacitor area is adjacent to the substrate or not to the contact electrode.
