Abstract
Surface and bulk traps along with positive oxide charge accumulation h ave been found to be generated in metal-oxide-semiconductor capacitors , when subjected to negative air corona discharge at slightly reduced pressure (congruent-to 10(-1) Torr). The effects are neutralized and d evice quality improved when annealed at 200-degrees-C in air. The bulk traps and a fraction of oxide charges were annealable when kept at ro om temperature for several months. The results have been analyzed by N icollian-Goetzberger's conductance technique and a plausible explanati on is given.
