Abstract

Wide band gap hydrogenated amorphous silicon oxide(a-SiOx:H) films were prepared by radio frequency plasma enhanced chemical vapor deposition(RF-PECVD) method. Nitrous oxide(N2O), hydrogen(H2), silane(SiH4) were used as source gases. With the increase of N2O/SiH4 ratio from 0.5 to 2, the optical band gap of films changed in the range of 1.93~2.65eV, and the hydrogen and oxygen contents were increased as well. The microstructure factor(R*) was used to characterize the degree of defect of films, and it was found that the increase of oxygen content could reduce the defect states. Moreover, we also studied the influence of RF power on the process of preparation. After comprehensive analysis, we got the best quality of films with optical band gap of 2.27eV and refractive index of 2.21 when N2O/SiH4 ratio is 1 and RF power is 90W.
