Abstract
Capacitor devices are formed in an essentially vertically extending fashion in order to achieve an essentially three-dimensional configuration or a configuration extending into the third dimension. A contacting of plug regions is performed after producing the capacitor devices. Such capacitor devices provide an increased integration density in a semiconductor memory device.
