Abstract
A vertical electrical device includes a region in a substrate extending from a surface of the substrate, the region having an inner wall and an outer wall circumscribing the inner wall. An inner electrically conductive layer is disposed on the inner wall and an outer electrically conductive layer is disposed on the outer wall, with an electrically insulative material disposed between the inner and outer layers. An electrical conductor in the substrate is bounded by the inner electrically conductive layer.
