Abstract
A method used in forming an array of capacitors comprises forming an array of vertically-elongated first capacitor electrodes that project vertically relative to an outer surface. An insulative ring is formed circumferentially about individual vertically-projecting portions of the first capacitor electrodes. The insulative rings about immediately-adjacent of the first capacitor electrodes in a first straight-line direction are laterally directly against one another. The insulative rings about immediately-adjacent of the first capacitor electrodes in a second straight-line direction that is angled relative to the first straight-line direction are laterally-spaced from one another. A capacitor insulator is formed over sidewalls of the first capacitor electrodes. At least one second capacitor electrode is formed over the capacitor insulator. Additional methods, including structure independent of method, are disclosed.
