ABSTRACT:
A high voltage capacitor structure for integrated circuits or the like. The capacitor includes a provision for equalizing charge when multiple capacitors are series coupled. Charge is equalized by a SiN layer overlaying, and in contact with one terminal of, the capacitor. A ground ring surrounds the capacitor structure and is also overlayed by, and in contact with, the SiN layer.
