Lifetime prediction of InGaZnO thin film transistor for the application of display device and BEOL-transistors

•Lifetime prediction model of InGaZnO TFTs for display and BEOL transistors.•Lifetime is proportional to the inverse square-root of VGS in the exponential term under high VGS and low VDS.•Lifetime is proportional to the inverse of VDS in the exponential term under low VGS and high VDS.
