Abstract
Description
기판 상에 카운터 전극과 게이트 버스 라인 및 게이트 전극 등의 형성이 완료되면 게이트절연막의 형성이라든지 TFT채널로 사용되는 a-Si;H막, 소오스/드레인과의 오믹접촉을 위한 n+ a-Si;H막을 순차적으로 형성하여 패터닝처리가 이루어지게 되며, 액정셀의 동작을 위한 화소전극의 형성은 투명전극재료인 ITO를 이용하여 행해지게 되고, 액정셀에 인가된 신호전압을 유지시키기 위한 축적용량(Storage capacitor)는 게이트절연막을 사이에 개재시킨 상태로 화소전극(ITO)을 게이트전극의 일부인 축적용량전극과 중첩시킴으로써 형성된다.
