Abstract
A first capacitor electrode and at least part of a second capacitor electrode of a capacitor are produced in depressions of an auxiliary layer by electroplating. The auxiliary layer is then removed and at least partially replaced by a capacitor dielectric. The first capacitor electrode and the part of the second capacitor electrode may be composed of a metal, for example platinum. The capacitor dielectric can be composed, for example, of barium-strontium-titanate.
