Abstract:
1. A device comprising: a semiconductor substrate with a planar surface; a semiconductor nanopillar on the semiconductor substrate and substantially perpendicular to the planar surface; an insulating layer covering the semiconductor nanopillar; a conductive layer covering the insulating layer, wherein all space between the conductive layer and the semiconductor nanopillar is completely filled by the insulating layer, wherein the conductive layer and the insulating layer are devoid of an end portion thereof, thus exposing an uninsulated pillar end of the semiconductor nanopillar; and a functional layer covering the conductive layer, wherein an insulating layer end of the insulating layer protrudes beyond a conductive layer end and terminates before the uninsulated pillar end of the semiconductor nanopillar,
