Abstract:
1. A method of forming a plurality of capacitors comprising: depositing a first material over a substrate; depositing a fluid pervious layer comprising at least one of nanotubes and nanowhiskers over the first material; forming a plurality of spaced capacitor electrode openings into the layer and into the first material; forming a plurality of capacitor electrodes within the openings; after forming the plurality of capacitor electrodes, etching the first material through the layer effective to expose outer lateral sidewalls of the capacitor electrodes below the layer and leaving at least some of said layer over the substrate proximate the plurality of capacitor electrodes; and after said etching, depositing capacitor dielectric material and capacitor electrode material over at least some of the outer lateral sidewalls below the layer exposed by said etching.
