摘要：

We propose fluorinated silicon oxide (SiOF) as the ion-stopper of bottom-gate amorphous silicon thin film transistors (a-Si:H TFT's). The low dielectric constant SiOF on both back-channel of the TFT and the crossover regions of gate/data lines can contribute to reducing the RC delay of the gate pulse signal in active-matrix liquid-crystal displays. Besides, an a-Si:H TFT with a SiOF stopper had an improved performance compared to a widely-employed silicon nitride (SiNx) stopper TFT because the fluorine incorporation reduces the interface state density between a-Si:H and SiOF.
