Claims (6)
- 도전층 상부에 콘택홀이 형성된 절연막을 형성하고 절연막 및 콘택홀에 금속박막을 증착하여 금속박막이 평탄화되도록 형성하는 방법에 있어서, 상기 절연막 및 콘택홀 상부에 소정의 챔버내에서 150℃ 이하의 온도조건에서 제1금속박막을 전체금속 박막 두께의 30% 증착시키는 단계와, 또다른 챔버로 이동하여 상기 제1금속박막 상부에 400℃ 이상의 조건에서 제2금속박막을 전체 금속 박막 두께의 70% 정도를 증착하는 단계로 이루어져 상기 콘택홀 및 절연막 상부에서 금속박막이 평탄하게 되는 것을 특징으로 하는 금속박막의 평탄화 형성방법.
- 제1항에 있어서, 상기 제1금속박막을 증착하는 단계전에 400℃ 이상에서 상기 절연막 및 콘택홀에 약 2분정도 가스분출(Degassing)시킨다음 상온으로 낮추는 것을 특징으로 하는 금속박막의 평탄화 형성방법.
- 제1항에 있어서, 상기 제2금속박막을 증착하는 단계전체 400℃ 이상에서 상기 제1금속박막을 약 1분정도 가열시키는 것을 특징으로 하는 금속박막의 평탄화 형성방법.
- 제1항에 있어서, 상기 제1금속박막을 소정의 챔버에서 증착하고, 제2금속박막을 또다른 챔버내에서 증착하는 단계는 스퍼터링 장비를 이용하여 연속적으로 실시되는 것을 특징으로 하는 금속박막의 평탄화 형성방법.
- 제1항에 있어서, 상기 도전층을 산화막을 질화물을 사용되는 것을 특징으로 하는 금속박막의 평탄화 형성방법.
- 제1항에 있어서, 상기 제1금속박막 및 제2금속박막은 알루미늄 또는 알루미늄 합금을 사용하는 것을 특징으로 하는 금속박막의 평탄화 형성방법.
