Abstract
미세 패넌을 형성 할 수 있으며, 동시에 그 패턴 크기를 증가시키는 것이 용이한 마스크에 관하여 개시한다.Disclosed is a mask that can form a fine pann and, at the same time, is easy to increase its pattern size.
본 발명은 투명한 기판 및 차광막 패턴을 마스크로서, 인접한 차광막 패턴 사이 및 상기 차광막 패턴의 둘레에 다른 부분을 투과한 빛과 180도의 위상차를 가지며 투과율을 조절 위상 반전 패턴을 가지는 것을 특징으로 한다. 본 발명의 마스크를 사용하여 형성된 포토레지스트패턴은 사이의 간격을 충분히 최소화하여 종래의 경우에 비하여 상기 포토레지스트 패턴의 크기를 증가시켜서 후속 공정에서 접촉창의 정렬 여유를 증가시킨다.The present invention is characterized in that a transparent substrate and a light shielding film pattern are masked, and have a phase difference of 180 degrees with light transmitted through other portions between adjacent light shielding film patterns and around the light shielding film pattern, and a transmittance control phase reversal pattern. The photoresist pattern formed by using the mask of the present invention sufficiently minimizes the gap between them, increasing the size of the photoresist pattern as compared with the conventional case, thereby increasing the alignment margin of the contact window in a subsequent process.
