Patent ID: 8450164

Claim:
A method of forming a plurality of capacitors, comprising: providing a substrate comprising a capacitor array area, a circuitry area other than the capacitor array area, and an intervening area between the capacitor array area and the circuitry area; an insulative material received over the capacitor array area and the circuitry area, the capacitor array area comprising a plurality of capacitor electrode openings within the insulative material received over individual capacitor storage node locations, the intervening area comprising a trench within the insulative material; forming conductive material within the capacitor electrode openings and within the trench to line the capacitor electrode openings and the trench to less than completely fill the trench, the conductive material within the trench and the insulative material of the circuitry area having an elevationally outer interface laterally therebetween; forming covering material atop the interface, over all of the circuitry area, and laterally over an upper portion of inner sidewalls of the conductive material within the trench, the covering material not laterally covering an entirety of the inner sidewalls of the conductive material within the trench; etching the insulative material within the capacitor array area effective to expose outer sidewall portions of the conductive material within the capacitor array area, said etching of the insulative material beginning while the covering material is received over all of the circuitry area; and incorporating the conductive material within the capacitor array area into a plurality of capacitors.
