WebGuard rings were p regions and formed by an ion implantation. Channel and source regions were similar. In addition, ion implantation to the junction field-effect transistor regions was introduced to improve the on-resistance of MOSFETs. The ion implantation was carried out at 500°C, then an activated anneal was done at 1800°C. Web22 cm2 /Vs was measured from a test MOSFET.
