Abstract
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 material defines an opening extending to the upper surface of the floating gate conductor, the material comprising a first dielectric underlying a second dielectric. A conductive element contacts the upper surface of the floating gate conductor and extending a distance along a sidewall of the opening.
