In this study, the AZO thin films were prepared as a function of oxygen gas flow ratio at room temperature by FTS(Facing Targets Sputtering) apparatus using Zn:Al(metal)-Zn:Al(metal) or Zn(metal)-ZnO:Al(ceramic). The film thickness, crystalline and electric properties of AZO thin film was evaluated by $\alpha$-step, XRD and 4-point probe. In the results, the resistivity of AZO thin film was shown the lowest value about 8${\times}$10$^{-2}$ $\Omega$-cm(Zn:Al-Zn:Al), 3${\times}$10$^{-1}$ $\Omega$-cm(Zn-ZnO:Al) at the oxygen gas flow ratio 0.3. And the AZO thin film has good crystalline at oxygen gas flow ration 0.4, using Zn:Al-Zn:Al targets.
