摘要:
A method of fabricating a semiconductor device is provided. The method includes forming a mold for forming a storage electrode, forming sacrificial spacers at side walls of openings in the mold, forming a conductive film for a storage electrode along the inside of the openings, removing the mold by a wet etching process, removing the sacrificial spacers by a dry etching process, and sequentially forming a dielectric film and an upper electrode on the storage electrode.
