Abstract
A structure and method for dissipating charges comprising an underlying dielectric layer disposed over capacitor plates of sensor circuitry a gap being formed conformally between adjacent plates and a topographic discharge grid over the underlying dielectric layer and wherein the topographic discharge grid fills at least a portion of the gap between the plates over the dielectric layer and diffuses electrostatic charges at the surface of the integrated circuit.
