Claims (2)
- 반도체 제조용 마스크의 크롬패턴 형성방법에 있어서, 공지의 방법으로 석영유리기판상에 표면이 불균일한 다수의 크롬패턴이 형성된 상태에서, 그 상부에 음감광막을 도포한 후 후면 노광을 실시하는 단계와, 상기 단계로부터 노광된 음감광막을 현상하여 크롬패턴 간의 석영유리기판에만 상기 음감광막을 패턴화하는 단계와, 상기 단계로부터 크롬 습식식각 용액에 담그어 크롬패턴의 상부면 및 음감광막과의 경계면을 식각하여 선폭이 좁아진 크롬패턴을 형성하는 단계와, 상기 단계로부터 스퍼터링 방식으로 빛 차단막을 형성하는 단계와, 상기 단계로부터 상기 음감광막을 제거하여 상기 석영유리기판 상부에 선폭이 좁아진 크롬패턴과 그 둘레에 형성된 빛 차단막으로 된 표면이 균일한 크롬패턴을 완성하는 단계로 이루어지는 것을 특징으로 하는 반도체 제조용 마스크의 크롬패턴 형성방법.
- 제1항에 있어서, 상기 빛 차단막은 크롬, Al2O3, Au, Ag중 어느 하나로 형성되는 것을 특징으로 하는 반도체 제조용 마스크의 크롬패턴 형성방법.
