Positive gate-bias and temperature stress were performed on the respective metal-oxide thin-film transistors as fabricated and stored in air ambiance for three months. An abnormal negative shift of the transfer characteristics was observed, and a channel width-dependence of device degradation occurred after long-term storing.
