Claims (1)
- 반도체기판(1), 상기 반도체기판(1)상의 절연층(2)에 매립되어 있는 전도층(3)과의 접속을 이루는 반도체 소자의 금속 배선 식각 방법에 있어서, 전도층(3)에 콘택을 형성 하기 위하여 감광막(P/R)으로 마스크 패턴하고 상기 절연층(2)을 식각하여 상기 전도층(3)에 콘택홀을 형성한 다음에 선택 텅스텐(4)을 증착하는 제1단계, 상기 제1단계 후에 금속(5)을 증착하고 상기 금속(5)과 텅스텐(4)을 소정의 크기로 접속을 이루게 하기위하여 감광막을 증착하여 패턴을 형성하는 제2단계, 및 상기 제2단계 후에 상기 금속(5)을 소정의 크기로 형성하고 소정의 크기로 형성 되어진 상기 금속(5)의 정형으로 과다증착된 텅스텐(4)을 식각하는 제3단계로 구비되는 것을 특징으로 하는 반도체 소자의 금속 배선 식각 방법.
