Patent ID: 8318578

Claim:
A method of forming a capacitor, comprising: providing base material having an opening therein over a node location on a substrate; depositing a bridging material over the base material and across the base material opening, the base material opening comprising a void beneath the bridging material; depositing covering material over the bridging material that is received over the base material and across the base material opening, the covering material comprising an outer antireflective layer; etching an opening through the covering material to the bridging material received across the base material opening; etching through the bridging material through the covering material opening; forming a first capacitor electrode within the covering material opening and within the base material opening in electrical connection with the node location, the forming of the first capacitor electrode comprising removal of the outer antireflective layer; and forming a capacitor dielectric and a second capacitor electrode operatively adjacent the first capacitor electrode.
