Abstract

We investigated AC bias stress instability of indium-gallium-zincoxide (IGZO) Thin-film transistors (TFTs). AC bias frequency dependence showed different aspect in IGZO TFTs and a-Si:H TFTs. Influencing factors to AC bias frequency dependence of instability is charge accumulation characteristic under negative bias stress, and detrapping characteristics of shallow trapped charges under positive bias stress.
