The BCE a-IGZO TFT covered by Red C/F shows more negative Vth, which can be suppressed by optimized PV1 deposition condition. After two month storage, the BCE a-IGZO TFT with good PBTS stability shows poor NBTS stability. We used SiOx/SiNx bi-layer PV1 to achieve good PBTS and NBTS stability, simultaneously.
