Abstract

A sensor is provided. The sensor includes a conductive substrate having side-walls; a dielectric layer overlaying a first surface of the conductive substrate, the dielectric layer including a gate dielectric having a first thickness and a field dielectric having a second thickness; a sensing layer overlaying a first surface of the gate dielectric; a non-conductive carrier wherein a second surface of the conductive substrate overlays a portion of the non-conductive carrier; and an insulating layer conformally coating at least the side-walls of the conductive substrate, wherein a first surface of the sensing layer is uncoated by the insulating layer.
