Zusammenfassung:A semiconductor device includes a substrate and a plurality of storage nodes on the substrate and extending in a vertical direction relative to the substrate. A lower support pattern is in contact with the storage nodes between a bottom and a top of the storage nodes, the lower support pattern spaced apart from the substrate in the vertical direction, and the lower support pattern having a first maximum thickness in the vertical direction. An upper support pattern is in contact with the storage nodes above the lower support pattern relative to the substrate, the upper support pattern spaced apart from the lower support pattern in the vertical direction, and the lower support pattern having a second maximum thickness in the vertical direction that is greater than the first maximum thickness of the lower support pattern.
