In this study, we fabricated the indium gallium zinc oxide (IGZO), zinc oxide (ZnO), aluminum zincoxide (AZO). oxide and silver are deposited by magnetron sputtering and thermal evaporator, respectively transparency and energy band gap were changed by the thickness of silver layer. To fabricate metal oxide metal(OMO) structure, IGZO sputtered on a corning 1,737 glass substrate was used as bottom oxide material and then silver was evaporated on the IGZO layer, finally IGZO was sputtered on the silver layer we get the final OMO structure. The radio-frequency power of the target was fixed at 30 W. The chamber pressure was set to 6.0×10-3Torr, and the gas ratio of Ar was fixed at 25 sccm. The silver thickness are varied from 3 to 15 nm. The OMO thin films was analyzed using XRD. XRD shows broad peak which clearly indicates amorphous phase. ZnO, AZO,OMO show the peak [002] direction at 34°. This indicate that ZnO, AZO OMO structure show the crystalline peak. Average transmittance of visible region was over 75%, while that of infrared region was under 20%. Energy band gap of OMO layer was increased with increasing thickness of Ag layer. As a result total transmittance was decreased.
