Description
Claims (4)
- 기판위에 통상의 방법으로 필드산화막 및 게이트를 형성하는 단계, 전체적으로 BPSG막을 형성하고 이 위에 하층감광제로서 평탄화용 폴리머막과 상승감광제로서 음성감광제막을 차례로 형성하는 단계, 상층감광제인 음성감광제막에만 포토/에치 공정을 실시하여 콘텍트 마스크를 형성하는 단계, 상기 콘텍트 마스크에 알루미늄막을 원하는 소정의 각도로 선택 증착하는 단계, 이 알루미늄막을 마스크로 알루미늄이 증착되지 않은 부분의 하부막만을 건식에치하여 콘텍트홀을 형성하는 단계가 차례로 포함됨을 특징으로하는 모스소자의 콘텍트홀 형성방법.
- 제1항에 있어서, 상층감광제인 음성감광제와 하층감광제인 평탄화용 폴리머 두께는 각각 약 0.5㎛이상으로 함을 특징으로 하는 모스소자의 콘텍트홀 형성방법.
- 제1항에 있어서, 알루미늄막 증착시 증착각도는 약 10~170°범위의 것으로하고 증착두께는 약 0.01~0.3㎛ 범위의 것으로 함을 특징으로하는 모스소자의 콘텍트홀 형성방법.
- 제1항에 있어서, 상층감광제인 음성감광제막의 각 패턴간의 최단 거리는 약 2㎛로 함을 특징으로 하는 모스소자의 콘텍트홀 형성방법.
