Abstract:
A portion of an integrated circuit package, comprising:a sensor chip havinga dielectric layer over a plurality of conductive plates serving as capacitive sensor electrodes, the dielectric layer isolating the conductive plates, anda conductive layer disposed over at least a portion of the dielectric layer and disposed over one or more conductive plates or regions between conductive plates, wherein the conductive layer dissipates an electrostatic charge in a manner that prevents the electrostatic charge from reaching the plurality of conductive plates, the conductive layer having a contact region between a central region of the sensor chip and a periphery of the sensor chip;a support having a ground, the sensor chip being affixed to the support; anda conductive material around a portion of the periphery of the sensor chip and contacting the contact region of the conductive layer, wherein the conductive material connects the conductive layer to the support ground.
