A MOS circuit arrangement includes a silicon substrate, a semiconductor device, a field oxide layer, and a poly-protective layer. The silicon substrate has a conductive doping incorporated therein, wherein the semiconductor device is electrically connected with the silicon substrate. The field oxide layer is formed on the silicon substrate at a position spaced apart from the terminal of the semiconductor device to form an active region between the field oxide layer and the semiconductor device. The poly-protective layer deposited on the active region to communicate the field oxide layer with the terminal of the semiconductor device, wherein the poly-protective layer provides a junction breakdown path between the semiconductor device and the silicon substrate to increase a junction breakdown voltage of the semiconductor device.
