| 抄録: | This is to study on the advantage of plasma-less deposition in catalytic chemical vapour deposition (Cat-CVD), often called hot-wire CVD. The effects of plasma damage are particularly studied by the performance of amorphous-silicon thin film transistors (a-Si TFTs), since it is strongly affected by the property of an interface between a gate insulating film and an a-Si film. It is found that the plasma damage at the interface affects on off-current of TFT, and that the off-current of Cat-CVD a-Si TFT is much lower than that of a-Si TFT in which all films are prepared by the conventional plasma-enhanced CVD (PECVD). The off-current of Cat-CVD a-Si TFTs is likely to increase and approach to the same level as the off-current of PECVD a-Si TFT, when Cat-CVD a-Si is exposed to weak plasma. In addition, since the off-current is so low, when the ratio of the channel width (W) to the channel length (L) is adjusted, the on-current can be increased up to the same level as the on-current of poly-crystalline silicon (poly-Si) TFT with keeping the off-current on the same level as that of poly-Si one. That is, it is concluded that a-Si TFT with current drivability equivalent to poly-Si TFT can be produced by using plasma-less Cat-CVD method for preparing films used in TFTs. |
