1. A vertically separated electrode structure comprising:
a substrate; a polymeric material post on the substrate, the post having a height dimension extending away from the substrate to a top defined by a length dimension and a width dimension over the substrate, the post having an edge along the height dimension; an inorganic material cap on the top of the post, the cap covering the top of the post in the length dimension and the width dimension of the post, the cap extending beyond the edge of the post in at least the width dimension to define a first reentrant profile; a first electrode located over the cap; a second electrode located over the substrate and not over the post and adjacent to the edge of the post in the reentrant profile such that a distance between the first electrode and second electrode is greater than zero when measured orthogonally to the substrate surface, the first electrode and second electrode have the same material composition and layer thickness, a conformal dielectric material layer on the cap, the edges of the post, and at least a portion of the substrate, the conformal dielectric layer being located at least between the first electrode and the cap, the first electrode having an end and the second electrode having an end, wherein the end of the first electrode and the end of the second electrode are vertically aligned. |
