There has been a question as to when the oxide damage occurs during plasma etching process. In this paper, we performed experiments to investigate when the plasma etch damage is done to the oxide. Plasma induced oxide charging occurs mainly during the over-etch time. There is no measurable additional damage during the moment of plasma turn-on and off.
