In-Si-O (ISO) thin films were investigated by X-ray reflectivity (XRR) and X-ray diffraction (XRD) techniques, and the operation of TFTs were characterized by a conventional three-probe method. XRR results suggested that as the annealing temperature increased, the film thickness decreased. In addition, according to XRD measurement, the ISO film started crystalline from 850 °C regardless the film thickness. The best ISO TFT showed the value of VT of –5 V, µ of 1.32 cm2/Vs, SS of 1 V/dec, and on/off current ratio about 107.
