Abstract
A semiconductor structure having electrical conductors positioned over each other, but electrically isolated from each other, is disclosed. The lower conductor has a recess in its upper surface, and the recess is at least partially filled with an oxide-type material, thereby isolating the lower conductor from the upper conductor. These conductors would normally contact each other because of the somewhat imprecise patterning and etching steps used to fabricate a multitude of conductive elements, e.g., in a very dense semiconductor structure. Stacked capacitor cells incorporating this structure are also disclosed.
