A method of producing a ferroelectric semiconductor memory, includes forming a switching transistor on a semiconductor substrate, applying an insulating layer to the switching transistor and then forming a storage capacitor, with electrodes of platinum and a ferroelectric or paraelectric dielectric, on the insulating layer. In order to protect the dielectric from being penetrated by hydrogen during further process steps, a first barrier layer is embedded into the insulating layer and, after completion of the storage capacitor, a second barrier layer, which bonds with the first barrier layer, is deposited.
