Abstract
In this work, we study threshold voltage (Vth) shift degradation in amorphous IGZO (a-IGZO) TFTs. The TFTs employ the bottom-gate staggered structure with an etch stopped layer. An improvement is presented to well known stretched-exponential equation for the Vth shift, and a systematic extraction method is provided. The Vth shift in a-IGZO TFTs is estimated quantitatively under different gate bias stress and temperature. Good agreements are obtained between calculated results and measured data.
