Abstract
A semiconductor device including storage nodes of a capacitor and a method for manufacturing the same are provided. Bit lines are formed on a semiconductor substrate, and protection layers are formed to cover and protect the bit lines. Conductive contact pads are formed between the bit lines and are level with the top surfaces of the protection layers. A node supporting layer is formed to cover the conductive contact pads and the protection layers. An etching stopper is formed on the node supporting layer. The mold layer, the etching stopper, and the node supporting layer are patterned, thereby forming opening holes exposing the conductive pads. Storage nodes are formed in the opening holes and have the shape of the profile of the opening holes. The mold layer exposed by the storage nodes is removed, thereby exposing the outer wall of each of the storage nodes positioned above the etching stopper.
