Temperature effect on antenna protection strategy for plasma-process induced charging damage

The leakage current of different drain-well diodes for plasma-charging protection has been simulated at high temperature. The simulation shows that the high ambient temperature, especially during plasma deposition process, enormously enhances the efficacy of the protection diodes in protecting thin oxide. The efficacy of different diodes has been compared by simulation and experiment. Based on our discoveries, a strategic protection scheme for plasma-process induced damage (PPID) is proposed.
