We have looked into the effect of substrate temperature and different ambient gases on the properties of IGZO films for the TCO.To achieve this goal, IGZO films were deposited by one of the PVD deposition, RF magnetron sputtering. We deposited IGZO films at various temperature(RT~400℃) and RT and 300℃ with gas(H2, O2) flow rate. Experiments were conducted while setting up the hydrogen and oxygen gas flow rate from 0.1sccm to 1.0sccm for seeing how the hydrogen and oxygen gas impacts on the IGZO films deposited at Room temperature and 300℃ showed amorphous structure. The lowest resistivity value was 0.379× Ω·cm when the IGZO film was deposited at 300℃ and set up at 1sccm. As the oxygen vacancy rate increased, the resistivity intended to decrease. In conclusion, Oxygen vacancy affects the IGZO thin film’s electrical characteristic.
