Abstract
Band electrode arrays, methods of manufacturing, and a method of using are disclosed. The arrays have individually addressable band electrodes such that diffusion layers of the band electrodes overlap. An exemplary method of manufacturing may comprise: a first insulating layer is disposed on a substrate; a first band electrode is disposed on the first insulating layer; a second insulating layer is disposed on the first insulating layer and completely covers the first band electrode; a second band electrode is disposed on the second insulating layer; a third insulating layer is disposed on the second insulating layer and completely covers the second band electrode; the first and second band electrodes are electrically insulated from each other and individually addressable; cross-sectional surfaces of the first and second band electrodes are exposed on the test surface; and these exposed cross-sectional surfaces substantially overlap each other in a direction perpendicular to the substrate.
