Abstract
Disclosed is a method for forming a capacitor of a semiconductor device. The method comprises the steps of: forming a nitride film for storage electrode on a semiconductor substrate; forming an oxide film for storage electrode on the nitride film; selectively etching the oxide film and the nitride film to define a storage electrode region; forming a conductive layer for storage electrode on the semiconductor substrate including the storage electrode region; forming a gap-filling nitride film on the semiconductor substrate to fill up the storage electrode region; performing a CMP process using the oxide film as a polishing stop layer to form a storage electrode; and removing the gap-filling nitride film.
