Abstract:
1. A method of forming a plurality of capacitors, comprising: forming a plurality of capacitor electrodes, an elevationally inner material laterally about the capacitor electrodes, an elevationally outer material laterally about the capacitor electrodes, a first material laterally about the capacitor electrodes elevationally inward of the inner material, a second material laterally about the capacitor electrodes elevationally between the inner and outer materials; forming openings to extend through the outer material and the second material; after forming the openings, removing all remaining of the second material through the openings from being laterally about the capacitor electrodes between the inner and outer materials, the removing of the second material being conducted selectively relative to the capacitor electrodes and the inner and outer materials; after removing all remaining of the second material through the openings from being laterally about the capacitor electrodes between the inner and outer materials, removing all remaining of the first material through the openings from being laterally about the capacitor electrodes between the inner and outer materials; and incorporating the capacitor electrodes into a plurality of capacitors.
