Abstract

니켈이 비정질 실리콘막 위의 주변회로 섹션과 화소 섹션에 이들을 결정화시키기 위하여 도입된다. 게이트 전극 및 다른 것을 형성한 후, 소스, 드레인 및 채널이 불순물 도핑에 의해 형성되고, 레이저가 결정화를 개선시키기 위하여 조사된다. 그후, 전극/배선이 형성된다. 이에 의해,주변회로 섹션안의 박막 트랜지스터가 캐리어의 흐름 방향에 평행한 방향으로 결정성장된 결정성 실리콘으로 구성되고, 화소 전극 섹션안의 TFTs가 캐리어의 흐름에 수직인 방향으로 결정성 실리콘 막으로 구성된 활성 매트릭스타입 액정 디스플레이가 얻어질 수 있다.
