Patent ID: 7199005

Claim:
A method of forming a plurality of capacitors, comprising: forming metal over individual capacitor storage node locations on a substrate; forming a patterned masking layer over the metal, the patterned masking layer comprising openings therethrough to an outer surface of the metal, individual of the openings being received over individual of the capacitor storage node locations; forming a pit in the metal outer surface within individual of the openings; after the forming of a pit in the metal outer surface within individual of the openings, anodically oxidizing the metal through the openings effective to form a single metal oxide-lined channel in individual of the openings over the individual capacitor storage nodes; forming individual capacitor electrodes within individual of the channels in electrical connection with the individual capacitor storage node locations; and removing at least some of the metal oxide from the metal oxide-lined channels and incorporating the individual capacitor electrodes into a plurality of capacitors.
