Abstract: A capacitor dielectric can be between the storage node and the electrode layer. A supporting pattern can be connected to the storage node, where the supporting pattern can include at least one first pattern and at least one second pattern layered on one another, where the first pattern can include a material having an etch selectivity with respect to the second pattern.
