Abstract
A structure and method for dissipating charges comprising an underlying dielectric layer disposed over capacitor plates of sensor circuitry, and a conductive path and passivation layers disposed over the underlying dielectric layer wherein the conductive pad forms an electrically conductive path over at least a portion of the plates and diffuses electrostatic charges at the surface of the integrated circuit.
