Abstract
A method of forming an array of capacitors comprises forming a vertical stack above a substrate. The stack comprises a horizontally-elongated conductive structure and an insulator material directly above the conductive structure. Horizontally-spaced openings are formed in the insulator material to the conductive structure. An upwardly-open container-shaped bottom capacitor electrode is formed in individual of the openings. The bottom capacitor electrode is directly against conductive material of the conductive structure. The conductive structure directly electrically couples the bottom capacitor electrodes together. A capacitor insulator is formed in the openings laterally-inward of the bottom capacitor electrodes. A top capacitor electrode is formed in individual of the openings laterally-inward of the capacitor insulator. The top capacitor electrodes are not directly electrically coupled together. Structure independent of method is disclosed.
