Claims (1)
- 다층배선 구조를 가진 반도체 장치의 제조방법에 있어서, 반도체 기판상의 제1저온 절연산화막층(1)상에 상기 반도체 기판에 형성된 소자의 소정부분과 접촉을 하기위한 제1알루미늄 금속층(2) 도포하고 그 상부에 상기 알루미늄 금속층(2)의 힐록 발생을 방지하기 위한 내화성의 중간금속층을 도포하는 제1공정과, 사진 식각공정을 이용하여 상기 금속층(2)(3)에 에칭을 실시하여 제1금속배선 패턴을 형성하는 제2공정과, 전면에 금속물질층간의 절연을 목적으로 하는 저온 산화막(4)을 도포하는 제3공정과, 소정부위의 저온 산화막(4)과 중간금속층(3)을 같이 에칭하여 금속층간의 접촉을위한 접촉창(5)을 형성하는 제4공정과, 전면에 제2알루미늄 금속층(6)을 도포하여 제2금속배선 패턴을 형성하는 제5공정을 구비하여 상기 공정들의 연속으로 다층의 배선층을 형성함을 특징으로 하는 반도체 장치의 제조방법.
