Abstract
To achieve a highest possible integration density in a semiconductor memory device having storage capacitors as storage elements, the method according to the invention forms the capacitor devices in substantially vertically extending fashion, to, as a result, achieve a substantially three-dimensional configuration and an configuration extending into the third dimension for the capacitor devices, a contact connection of the storage capacitors being formed after the production of the storage capacitors.
