Abstract
Description
이러한 방법에 의해 중간층(146)을 형성한 다음에는 제거된 게이트 라인(122) 영역을 다시 연결시켜 주어야 한다. 이러한 작업은 픽셀부(126)의 TFT 부에서 중간층(146) 위에 소오스 및 드레인전극을 형성할 때 이루어져야 한다. 이를 위하여 도 6에 도시된 바와 같이 게이트 드라이버(124) 쪽의 게이트 라인(122)부와 픽셀부(126) 쪽의 게이트 라인(122)부 위에 형성된 중간층(146) 영역 일부를 사진 식각법을 통해 제거하여 콘택홀들(148,150)을 형성시킨다. 그 후 콘택홀(148,150)이 형성된 중간층(146) 상에 전극 물질을 전면 증착한다. 전극 물질을 증착한 다음에는 포토 레지스트 마스크 패턴을 이용하여 픽셀부에는 소오스전극과 드레인전극을 형성시키고, 게이트 라인부에는 끊겨진 게이트 라인(122)의 부분들이 서로 연결되게끔 콘택홀들(148,150)과 중간층(146) 상에 연결전극라인(152)을 형성시킨다. 끊겨진 게이트 라인(122)이 연결전극라인(152)에 의해 재연결되는 형태는 도 6에 도시된 바와 같다. 이로써 게이트 드라이버(124)의 회로부와 픽셀부(126)가 다시 연결되게 된다. 그 다음에는 종래와 마찬가지로 CVD 장비를 이용하여 패시베이션(Passivation)막(154)을 형성한다. TFT 부의 패시베이션막에 형성되는 콘택홀과 화소전극은 도면에 도시되어 있지 않다. 이러한 과정을 통해 액정표시소자의 하판이 완성되게 된다.
