1. An integrated circuit comprising:

  • sensor circuitry; and

    a passivation comprising;

    an insulating layer disposed over the sensor circuitry to electrically isolate the sensor circuitry; and

    a conductive discharge layer disposed over the insulating layer, wherein the discharge layer diffuses electrostatic charges to electronic components that dissipate the electrostatic charges if the passivation is contacted.
