Abstract
A storage capacitor, in particular a ferroelectric or paraelectric storage capacitor, and an associated contact-making structure are formed in such a way that the storage capacitor has a first electrode layer, a second electrode layer and a dielectric, ferroelectric or paraelectric capacitor intermediate layer. Proceeding from the plane of the surface of the insulation layer, the storage capacitor extends at least partly into the interior of the via contact and is electrically connected to the via contact.
