A method for fabricating a capacitor includes: forming a first silicon layer over a semiconductor substrate, where the first silicon layer is doped with a dopant; forming an undoped second silicon layer over the first silicon layer; forming an opening by etching the second silicon layer and the first silicon layer; forming a storage node in the opening; and removing the first silicon layer and the second silicon layer.

A capacitor includes a pillar-type storage node, a supporter disposed entirely within an inner empty crevice of the storage node, a conductive capping layer over the supporter and contacting the storage node so as to seal an entrance to the inner empty crevice, a dielectric layer over the storage node, and a plate node over the dielectric layer.

A capacitor includes a bottom electrode, a dielectric layer and a top electrode over a substrate. A RuXTiYOZ film is included in at least one of the bottom and top electrodes, where x, y and z are positive real numbers. A method of fabricating the capacitor through a sequential formation of a bottom electrode, a dielectric layer and a top electrode over a substrate includes forming a RuXTiYOZ film during a formation of at least one of the bottom electrode and top electrode, where x, y and z are positive real numbers.
