Patent ID: 7704828

Claim:
A method of fabricating a semiconductor device, the method comprising: forming an interlayer insulating film on a substrate; forming a mold insulating film on the interlayer insulating film, wherein forming the mold comprises forming contact regions in which at least one of the openings meets another adjacent opening; forming openings through the mold insulating film so as to form a mold; forming sacrificial spacers on the side walls of the openings; forming a conductive film along the inside of the openings in which the sacrificial spacers are formed; filling the inside of the openings, thereby forming sacrificial capping films; partially removing the sacrificial capping film and the conductive film to expose the top of the mold; removing the mold and the sacrificial capping film; removing the sacrificial spacer using a dry method, thereby forming storage electrodes; and sequentially forming a dielectric film and an upper electrode on the storage electrodes.
