    摘要: A semiconductor device, a semiconductor module, an electronic apparatus and methods of fabricating and manufacturing the same are provided. The semiconductor device includes a lower interconnection formed on a substrate, a plurality of control patterns formed on the lower interconnection, a plurality of lower contact plug patterns formed on the control patterns, a plurality of storage patterns formed on the lower contact plug patterns, a plurality of upper electrodes formed on the storage patterns, and a plurality of upper interconnections formed on the upper electrodes. The lower contact plug patterns each include at least two contact holes having different sizes, a plurality of sidewall patterns formed on inner sidewalls of the two contact holes and wherein the sidewall patterns have different thicknesses from one another. The semiconductor device further includes a plurality of electrode patterns conformably formed on the inside of the sidewall patterns and having size errors less than 10%, and a plurality of filling patterns formed inside the electrode patterns and completely filling the inside of the contact holes.
