Abstract

In one implementation, a chemical sensor is described. The chemical sensor includes a chemically-sensitive field effect transistor including a floating gate conductor having an upper surface. A dielectric material defines an opening extending to the upper surface of the floating gate conductor. A conductive element on a sidewall of the opening and extending over an upper surface of the dielectric material.
