Abstract

Electromagnetic shielding, transparent ITO coating layers have deposited on ocular lens substrate by magnetron sputtering. We investigated the effect induced by the substrate temperature on coating layer. The characteristics of the coating layers were analyzed using surface profiler, four-point probe, XRD, spectrophotometer and Auger Electron spectroscopy. As substrate temperature became higher, carrier concentration was increased and transmittance in the visible region was increased, too.

전자파 차폐 기능을 가지고 있는 ITO 코팅층을 안경 유리 기판위에 마그네트론 스퍼터링 방법으로 제조하였다. 코팅된 ITO 층을 surface, profiler, four-point probe, XRD, spectrophotometer 및 Auger electron spectroscopy를 사용하여 기판 온도가 코팅층의 특성 변화에 미치는 영향을 조사하였다. 기판의 온도가 높을수록 전자의 농도가 증가하였으며 가시영역에서 광투과율도 향상되었다.
