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 conductive element protrudes from the upper surface of the floating gate conductor into an opening. A dielectric material defines a reaction region. The reaction region overlies and extends below an upper surface of the conductive element.
