The Ce-Cr(-Ta) film are one of the most suitable candidates for perpendicular magnetic media. the control of the preparation conditions, such as Ar gas pressure P$\_$Ar/ substrates temperature T$\_$s/, films thickness $\delta$, deposition speed R$\_$d/, is considered to be important to attain ultra high density recording far perpendicular magnetic recording media. In this study, the Co-Cr thin films and Co-Cr-Ta thin films were deposited on the glass side substrates by using Facing Targets Sputtering apparatus(FTS). Crystallographic characteristics and magnetic characteristics were evaluated by X-ray diffractometry(XRD), Vibrating Sample Magnetometer(VSM) respectively.

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.

In this study, AZO(ZnO:Al) thin film were prepared by FTS(Facing Target Sputtering) system. The electrical, optical and crystallographic properties of AZO thin film with $O_2$ gas flow ratio have been investigated. The thickness, transmittance, crystal structure and resistivity of AZO thin film were measured by a-step, UV-VIS spectrometer, XRD and four-point probe, respectively. As a result AZO thin film deposited with the transmittance over 80% and the resistivity about $10^{-1}\Omega-cm$.

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 work, the ITO thin films were prepared by FTS (Facing Targets Sputtering) system under different sputtering conditions which were varying $O_2$ gas flow and input current. As a function of sputtering conditions, electrical and optical properties of prepared ITO thin films were measured. The electrical characteristics, surface roughness and transmittance of the ITO thin films were evaluated by Hall Effect Measurement, AFM, and UV-VIS spectrometer respectively. In addition, I-V properties of OLED cells were measured by 4156A(HP).

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].
