Abstract
The invention describes a method of fabricating the integration of high-voltage devices and low-voltage devices. The ion implantation steps for forming the isolation doping regions and the drafting doping regions in the high-voltage device are used to form simultaneously the anti-punch-through regions in the low-voltage device. The production of the integrated circuit is then finished with other process steps.
