Patent ID: 7919386

Claim:
A method of forming a plurality of capacitors, comprising: providing a plurality of capacitor electrodes within a capacitor array area over a substrate, the capacitor electrodes comprising outer lateral sidewalls, individual of the capacitor electrodes comprising a container shape; forming a retaining structure which engages the outer lateral sidewalls of the capacitor electrodes, the retaining structure being formed at least in part by etching a layer of insulative material which is not masked anywhere within the capacitor array area to form said retaining structure; and further comprising after forming the retaining structure, etching the retaining structure to reduce its size; the etched retaining structure at least in part supporting the plurality of capacitor electrodes; and incorporating the plurality of capacitor electrodes into a plurality of capacitors, the retaining structure remaining as part of a finished integrated circuitry construction incorporating the plurality of capacitors.
