摘要
The relation between threshold voltage for hydrogenated amorphous silicon thin film transistors (a-Si:H TFTs) and deposition conditions for hydrogenated amorphous silicon nitride (a-SiN x :H) films is investigated.It is observed that the threshold voltage, V th ,of a-Si:H TFT increases with the increase of the thickness of a-SiN x :H film,and the threshold voltage is reduced apparently with the increase of NH 3/SiH 4 gas flow rate ratio.
