Abstract

본 발명은 반도체 소자제조 공정에 있어서, 금속선과 콘택 플러그를 동시에 형성하는 방법에 관한 것으로, 특히, 종래의 방법에 의해 웨이퍼상에 절연층과 콘택홀을 형성하고 그 상부에 에스오지 박막을 이용한 패턴 산화막을 증착한 후 그 상부에 감광막 패턴을 형성하고 다음에 습식식각으로 패턴 산화막을 선택적으로 제거하여 금속선이 형성될 부분과 콘택홀을 노출시키고 이 상태에서 규소주입을 통해 씨드 레이어를 형성하며 이어 패턴 산화막 상부에 형성된 감광막을 제거하고 이후 선택금속을 증착시킴으로써 콘택 플러그와 금속배선을 동시에 형성하는 방법에 관한 것이다.
