摘要
Choice of gate dielectric has a significant impact on device performance and lifetime. In this study, various polysilicon thin-film transistor (poly TFT) chemically vapor deposited (CVD) dielectrics including SiO2 (silicon dioxide), Si3N4-SiO2 (nitride-oxide i.e., NO) stacks and oxide-nitride-oxide (ONO) stacks have been investigated and several possible breakdown mechanisms are proposed based on electrical results and previous studies. The breakdown characteristics of the oxides depend on different parameters such as oxide thickness, temperature and polarity.
