不稳定性

Several common degradation phenomena were summarized from some recent typical research work on the reliability of low-temperature processed poly-silicon thin film transistors, which includes self-heating, hot carriers and negative gate bias temperature instability. Degradation mechanisms and models are presented as well as conclusions of their influences on various device parameters and typical stress conditions.
