摘要

Various kinds of silicondioxides (SiO_2) were systematically investigated by current-voltage and poly-Si TFT-characteristics. Without hydrogenation, oxide by TEOS-PECVD has the best TFT-characteristics. After plasma hydrogenation LPCVD-oxide has the best TFT-characteristics, with a mobility of 150 cm~2/Vs and an off-current of 0.4 pA.
