Patent ID: 7413950

Claim:
A method of forming a capacitor comprising: forming a storage node contact pad; forming a semiconductor substrate including a contact region, the storage node contact pad being electrically coupled to the contact region of the substrate; forming a mold layer on the semiconductor substrate; etching the mold layer to form the contact holes respectively exposing at least a portion of corresponding portions of the storage node contact pad; forming a storage electrode including at least two cylindrical conductive patterns, the at least two cylindrical conductive patterns being electrically coupled to the storage node contact pad; forming a dielectric layer on the conductive patterns; and forming a plate electrode on the dielectric layer, wherein forming the storage electrode comprises: forming a conductive layer on the mold layer, the storage node contact pad and the inner walls of the contact holes; forming a sacrificial layer on the conductive layer in the contact holes; and partially removing the sacrificial layer and the conductive layer until the mold layer is exposed such that the storage electrode includes at least two conductive patterns on the storage node contact pad and inner walls of contact holes.
