Abstract
A silicon on insulator (SOI) device is provided. The device includes an MOS capacitor coupled between voltage busses and formed in a monocrystalline semiconductor layer overlying an insulator layer and a semiconductor substrate. The device includes at least one electrical discharge path for discharging potentially harmful charge build up on the MOS capacitor. The MOS capacitor has a conductive electrode material forming a first plate of the MOS capacitor and an impurity doped region in the monocrystalline silicon layer beneath the conductive electrode material forming a second plate. A first voltage bus is coupled to the first plate of the capacitor and to an electrical discharge path through a diode formed in the semiconductor substrate and a second voltage bus is coupled to the second plate of the capacitor.
