摘要: To manufacture FeRAM memories in a particularly space-saving fashion and, thus, increase the storage density, a manufacturing method forms at least some of the multiplicity of capacitor devices used as storage elements with a multiplicity of individual capacitors that are connected in parallel with one another. The individual capacitors have ferroelectric or paraelectric dielectric regions with different coercitive voltages such that there is a resulting multiplicity of storage states for each of the individual capacitors.

摘要: 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.
