초록

We prepared the ITO/Ag multilayer thin films on soda-lime glass substrate by the Facing Target Sputtering System (FTS) at room temperature. To confirm the effect of Ag layer in ITO/Ag multilayer thin films, we have prepared various range of Ag layer in its thickness and investigated prior to the setting of ITO/Ag multilayer thin films. The thickness of Ag layer was controlled by the sputtering deposition time. Properties of as-prepared samples were investigated by using a four-point probe, UV-Visual spectrometer with a spectral visual range (400-800nm) and X-ray diffractometer (XRD). As a result, the transmittance of as-prepared samples turned out to be very low in the visible range due to light-scattering on the surface of thin film as the thickness of Ag layer got increased. However, reduction of phenomenon of light-reflection in visual range was observed around 20nm of Ag thickness. We prepared the ITO/Ag multilayer thin film with a resistivity of about 8×10-5 [Ω-cm] and a transmittance of more than 80 % at 550 nm.
