Abstract

A thin-film transistor includes a substrate, a semiconductor channel region, a gate insulating layer, a source region, a drain region, a source electrode, a drain electrode and a gate electrode. The thin-film transistor also includes a carrier injection terminal, and the carrier injection terminal can provide the semiconductor channel region with a carrier of which the polarity is opposite to that of a channel carrier when the thin-film transistor is conducting. The thin-film transistor can significantly reduce device degradation and threshold voltage shift caused by a dynamic hot carrier effect, thereby improving the reliability of a thin-film transistor device and a circuit and simplifying the complexity of the design of a threshold voltage compensation circuit. In addition, the thin-film transistor has low processing difficulty and has no influence on the normal operation of a device.
