[도 2]는 투명전도막을 선폭 100㎛ 가량의 광폭 레이저 빔으로 음각한 상태와 선폭 30㎛ 가량의 협폭 레이저 빔으로 음각한 상태를 촬영한 사진이다.
[도 3]은 광폭 레이저 빔과 협폭 레이저 빔을 혼용하여 투명전도막을 깎아내는 공정에 관한 모식도이다.
[도 4]는 투명전도선의 테두리 주위에 2차 여유면을 남겨 둔 후 상기 투명전도선의 방향을 따라 상기 2차 여유면을 깎아내는 공정에 관한 모식도이다.
[도 5]는 레이저 스크라이빙 기술을 이용하여 선폭 10~50㎛ 범위 내의 여러 가지 투명전도선을 형성시킨 상태를 촬영한 사진이다.
[도 6]은 레이저 빔의 파장에 따라, 투명전도막이 코팅된 기판의 UV-Vis-NIR 투과율과 투명전도막을 제외한 기판 자체의 UV-Vis-NIR 투과율을 비교한 그래프이다.
[도 7]은 투명전도막을 제외한 기판 자체의 UV-Vis-NIR 투과율이 투명전도막이 코팅된 기판의 UV-Vis-NIR 투과율보다 7% 이상 큰 파장대에 있는 레이저 빔을 이용하여 기판의 손상 없이 투명전도막을 깎아낸 상태를 촬영한 사진이다.
