Claims (5)
- 마스크를 이용한 노광 대상물의 투영 노광 방법에 있어서, 상기 마스크를 통과하는 광의 경로와 수직한 방향에 대하여 상면이 전체적으로 경사진 투명한 마스크 기판과 상기 마스크 기판의 하면에 규칙적으로 형성되어 있는 차광막 패턴을 이용하여 노광함으로써, 상기 경사진 마스크 기판으로 인하여 인접한 차광막 패턴들 사이에 위상차를 갖게 하는 것을 특징으로 하는 투영 노광 방법.
- 제1항에 있어서, 상기 위상차는 ndtanθ(n은 마스크 기판의 굴절율, d는 마스크의 피치, θ는 마스크 기판 상면의 경사진 각도)인 것을 특징으로 하는 투영 노광 방법.
- 상면이 광경로와 수직한 방향에 대하여 전체적으로 경사진 투명한 마스크 기판; 및 상기 마스크 기판의 하면에 규칙적으로 형성되어 있는 차광막 패턴을 구비하여, 상기 경사진 마스크 기판으로 인하여 인접한 차광막 패턴들 사이에 위상차가 발생하게 하는 것을 특징으로 하는 마스크.
- 제3항에 있어서, 상기 위상차는 ndtanθ(n은 마스크 기판의 굴절율, d는 마스크의 피치, θ는 마스크 기판 상면의 경사진 각도)인 것을 특징으로 하는 마스크.
- 제1면이 광경로와 수직한 방향에 대하여 전체적으로 경사진 투명한 마스크 기판; 및 상기 제1면과 반대의 상기 마스크 기판의 제2면에 규칙적으로 형성되어 있는 차광막 패턴을 구비하는 것을 특징으로 하는 마스크.
