Abstract
The effects of low temperature deuterium annealing on plasma process induced damage were examined for devices with a thin gate oxide. The devices were exposed to the plasma during poly-Si gate or metal processes, and the device characteristics were monitored by charge pumping and current-voltage measurements. It was observed that the metal process induced more plasma damage than the poly-Si gate process. The deuterium (D2) annealing had little effect on oxide damage, but it was very effective in reducing the interface damage. After D2 annealing, the devices showed a very low level of interface states, and the strength to withstand electrical stress was also enhanced. To maximize D2 annealing effects, it is suggested that the D2 annealing should be made without any H2 annealing.
