Characteristics of ITO thin films on different substrates

기판의 종류에 따라 제작한 ITO 박막의 특성

We prepared ITO thin films using Facing Targets Sputtering(FTS) method with various input currents at room temperature on Polycarbonate(PC) and Polyethersulfon(PES) substrates. As a function of sputtering conditions, electrical and optical properties of prepared ITO thin films were measured. The electrical, optical, structural characteristics of ITO thin films were evaluated by Hall Effect Measurement(EGK), X-Ray Diffractormeter(Rigaku) and UV-VIS spectrometer(HP) respectively. From the results, we obtained ITO thin films that have a resistivity of $4{\times}10^{-4}[{\Omega}-cm]$ on PC and $527{\times}10^{-4}[{\Omega}-cm]$ on PES. Also, the optical transmittances of all samples were over 80%.
