Patent ID: 7449391

Claim:
A method of forming a plurality of capacitor devices, comprising: providing a construction comprising a first material over a substrate; forming openings extending into the first material; the openings extending in an array comprising rows and columns; forming a first conductive layer within the openings, the first conductive layer within the openings forming container structures having outer sidewalls along the first material wherein the container structures are formed in the array defined by the openings and thus the container structures are within an array comprising rows and columns; providing a retaining structure which extends between and connects alternating pairs of the rows of the container structure array, the retaining structure being directly against the first conductive layer of the container structures; removing at least some of the first material to expose at least portions of the outer sidewalls of the container structures, the retaining structure retaining the container structures during the removal of the first material; forming a capacitor dielectric material along the exposed portions of the outer sidewalls and within the container structures; and forming a second conductive layer over the capacitor dielectric material.
