stress threshold

The mechanisms for a-Si ∶ H-TFT threshold voltage shift were analyzed. That is, the influence of charges injecting into SiN_x ∶ H gate insulator and the creation of meta-stable states in a-Si ∶ H to a-Si ∶ H-TFT threshold voltage shift under gate bias stress were analyzed.

分析了a-Si∶H-TFT阈值电压漂移的机理，即分析了栅偏应力下电荷注入到sin x∶H栅绝缘层和a-Si∶H中亚稳态的产生对TFT阈值电压漂移的影响。
