The present invention in one embodiment provides a method of forming an
electrode that includes the steps of providing at least one metal stud in
a layer of an interlevel dielectric material; forming a pillar of a first
dielectric material atop the at least one metal stud; depositing an
electrically conductive material atop the layer of the interlevel
dielectric material and an exterior surface of the pillar, wherein a
portion of the electrically conductive material is in electrical
communication with the at least one metal stud; forming a layer of a
second dielectric material atop the electrically conductive material and
the substrate; and planarizing the layer of the second dielectric
material to expose an upper surface of the electrically conductive
material.
