The ITO thin films were prepared by facing targets sputtering (FTS) system on polycarbonate (PC) substrate. The ITO thin films were deposited with a film thickness of 100 nm at room temperature. As a function of sputtering conditions, electrical and optical properties of prepared ITO thin films were measure. The electrical and optical characteristics of the ITO thin films were evaluted by Hall Effect Measurement (EGK) and UV/VIS spectrometer (HP), respectively. From the results, the ITO thin films was deposited with a resistivity $8{\times}10^{4}\;{\Omega}-cm$ and transmittance over 80 %.

The ITO thin films were prepared by Facing Targets Sputtering(FTS) method on polyethersulfon(PES) substrate. The ITO thin films were deposited with the film thickness of 100nm at room temperature and working gas pressure of 1 mTorr.

Because AZO thin film has the potential applications, Preparing AZO thin films on the polymer substrate has been widely studied. In this study, we prepared AZO thin films on polyethersulfon (PES) at room temperature. The AZO thin films were prepared at $O_2$ gas flow rate of 0.05 and sputtering power of 100W with different film thickness by facing targets sputtering method. The electrical, optical and crystallographic properties of AZO thin films were measured by Hall effect measurement system, UV/VIS spectrometer, SEM and XRD. From the results, we obtained AZO thin films with a low resistivity, a transmittance of over 80% and c-axis preferred orientation.

We prepared indium zinc oxide (IZO) thin film for cathode electrode such as an application of flat panel display by using the facing targets sputtering (FTS) method at room temperature. The effects of input power and film thickness were investigated with respect to physical and optical properties of films such as deposition rate, electrical properties, microstructure and transmittance. We could obtain properties of IZO thin films of under $10^{-3}\;{\Omega}-cm$ in resistivity and the thin films of over 90% in transmittance. Also, we obtained IZO thin films which were an amorphous structure.

We prepared ZnO:Al (AZO) thin films on polycarbonate (Pc) and polyethersulfon (PES). Because the polymer substrate has weak thermal resistance. The AZO thin films were deposited at room temperature by facing targets sputtering (FTS) method In the work, AZO thin films were deposited with different thickness in 1mTorr and $O_2$ gas flow rate 0.05. The electrical, optical and crystallographic properties were measured From the results, the resistivity of $7.3{\times}10^{-4}{\Omega}cm$ and transmittance of over 80% in visible range were obtained.

In this study, Al doped ZnO(AZO) thin film were prepared on glass substrates by FTS(Facing Targets Sputtering) system. We investigated electrical, optical and structural properties of AZO thin film with the substrate temperature of the R.T, $100^{\circ}C$, $200^{\circ}C$ and the post-annealing. The crystallinity of AZO thin film was increased with increasing the substrate temperature and post-annealing temperature $600^{\circ}C$. The remarkable change of the resistivity with the substrate temperature didn't found and the resistivity with post-annealing was increased slightly.

In this study Al electrode for OLED was deposited by FTS(Facing Targets Sputtering) system which can deposit thin films with low substrate damage. The Al thin films were deposited on the cell(LiF/EML/HTL/Bottom electrode) as a function of working gas such as Ar, Kr or mixed gas. Also Al thin films were prepared with working gas pressure (1, 6 mTorr ). The film thickness and I-V curve of Al/cell were evaluated by $\alpha$-step and semiconductor parameter (HP4156A) measurement. In the results, when Al thin film were deposited using pure Ar gas, the turn-on voltage of Al/cell was about 11[V]. And the turn-on voltage of Al/cell can be decrease to about 7[V].

We prepared ZnO thin films coating Ag on glass substrates at room temperature by using facing targets sputtering (FTS) method. ZnO thin films were deposited with same conditions. Ag with various thickness of thin films were used as intermediate layers. The electrical, optical and crystallographic properties of thin films were investigated by Four-Point probe, UV/VIS spectrometer and XRD. From the results, we could confirm that the thickness of Ag layer changes the electrical and optical performances of the multilayers.

We prepared the Al doped ZnO (AZO) thin film on polyethersulfon (PES) without any substrate heating by Facing Targets Sputtering (FTS) system. ZnO doped the content of Al 2 wt% was used and the sputtering conditions were gas pressure 1mTorr and input power 100W. The electrical, structural and optical properties of AZO thin films were investigated.
