Abstract
A semiconductor device for preventing the leaning of storage nodes and a method of manufacturing the same is described. The semiconductor device includes support patterns that are formed to support a plurality of cylinder type storage nodes. The support patterns are formed of a BN layer and have a hexagonal structure. The BN layer forming the support patterns has compressive stress as opposed to tensile stress and can therefore withstand cracking in the support patterns.
