Claims (5)
- 기판 상부에 패터닝된 금속막 상단에 탄소나노튜브로 이루어지는 전계 방출 표시 소자를 제조하는 방법으로서,상기 금속막 상단의 일 지점에 탄소나노튜브로 이루어지는 생장점을 형성시키는 단계와;탄소나노튜브를 다량 함유하고 있는 전해질 용액의 일 측에 대전 극판을 위치시키고, 상기 전해질 용액의 타 측에 탄소나노튜브의 생장점이 형성된 부분을 상기 대전 극판에 대향하도록 기판을 위치시키는 단계와;상기 대전 극판 및 기판 각각에 전원을 인가하여 전해질 용액에 함유된 탄소나노튜브를 상기 기판의 탄소나노튜브 생장점 부분에 전기화학적으로 부착시켜 탄소나노튜브 에미터를 형성시키는 단계를;포함하여 이루어지는 것을 특징으로 하는 전계 방출 표시 소자 제조방법.
- 제1항에 있어서,상기 탄소나노튜브 에미터 형성 단계 이후에는, 상기 금속막 상단에 부착된 탄소나노튜브 에미터와 금속막 사이의 결합력을 증진시키기 위해 상기 기판을 열처리하고 고전압을 인가하는 고온열처리 및 어노딕본딩 단계가 더욱 부가되는 것을 특징으로 하는 전계 방출 표시 소자 제조방법.
- 제1항에 있어서,상기 대전 극판 및 기판에 인가되는 전원은 직류, 교류, 펄스 중에서 선택되는 어느 하나인 것을 특징으로 하는 전계 방출 표시 소자의 제조방법.
- 제1항에 있어서,상기 금속막 상단의 생장점은 외부로 돌출되는 형태로 이루어지는 것을 특징으로 하는 전계 방출 표시 소자의 제조방법.
