Polymer 기판상에 제작된 AZO/Ag/AZO 다층박막

We prepared Al doped ZnO/Ag/Al doped ZnO on the polymer substrate by Facing Target Sputtering (FTS). FTS featured Facing Target Sputtering featured that deposition is stable at the low pressure, it has high plasma density and suppresses the substrate damage from energetic particles. We fixed to 50nm up and down thickness of AZO layer, respectively and that of intermediate Ag layer was adjusted with deposition time. In the result, AZO/Ag/AZO multilayer thin films have much better electrical conductivity than AZO single layer thin film. As increasing the thickness of Ag layer, the transmittance decreased.
