Patent ID: 7585741

Claim:
A method of forming a plurality of capacitor devices, comprising: providing a semiconductor construction which includes a first material over a semiconductor substrate; the first material having defined first, second, and third regions; the second region being between the first and third regions; forming a second material over the first material; the second material being across at least a portion of the first region and across an entirety of the third region; forming openings extending into the first region and forming a trench within the second region; forming a first conductive layer within the openings and within the trench, the first conductive layer within the openings forming container structures having outer sidewalls along the first material; forming a third material over the first conductive layer and over the second material; the third material extending within the container structures, extending within the trench, and also extending over an entirety of the second material that is across the third region; after forming the first conductive layer, second material and third material, removing at least some of the first material to expose at least portions of the outer sidewalls of the container structures; after removing said at least some of the first material, removing the third 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.
