Abstract
A capacitor is described which includes an inner capacitor plate having at least one sidewall; an oxidation barrier layer positioned in covering relation relative to the at least one sidewall; a capacitor dielectric plate positioned over the inner capacitor plate; and an outer capacitor plate positioned over the capacitor dielectric plate. In the preferred form of the invention, an insulating dielectric layer is positioned on the oxidation barrier layer, the insulating dielectric layer being of a different composition than the oxidation barrier layer.
