temperature on the initial electrical characteristics and photo-inducedinstabilities of amorphous indium gallium zinc oxide (a-IGZO) thin-film transistors (TFTs). The extracted electrical parameters from transfer curves suggest that a low-temperature treatment maintains a high density of defects in the IGZO
irrespective of treatment temperature. NBIS-induced critical instability occurs in the high-temperature-annealed TFT.

The rapid process of industrialization and
this work, we investigate the impact of annealing temperature on the initial electrical characteristics and photo-inducedinstabilities in a-IGZO TFTs. The obtained electrical parameters imply that low- and high-temperature annealing leverage the generation of defects in the active layer as well as its
