Claims (6)
- 기관 또는 막질이 형성된 기판상에 미세패턴을 형성하기 위한 사진식각방법에 있어서, 상기한 기판상에 UV 레지스트막과 DUV 레지스트막을 순차 적층하는 단계와, 포토마스크와 DUV 광원을 사용하여 DUV 노광 및 현상을 실시하는 단계와, UV 노광 후 현상을 거쳐 극미세패턴을 형성하는 단계로 이루어지는 것을 특징으로 하는 미세패턴형성을 위한 사진식각방법.
- 제 1 항에 있어서, DUV 노광은 50mJ/㎠ 이상 과다 노광을 실시하는 단계와 60초 이상 과다현상을 실시하여 0.3㎛ 이하의 극미세패턴된 DUV 레지스트 막으로 형상화하는 단계를 포함함을 특징으로 하는 미세패턴 형성을 위한 사진식각방법.
- 제 1 항에 있어서, UV노광은 소나기 노광이며 DUV 노광 및 현상에 의한 패턴(8)은 상기 UV 노광에 대하여 마스크인 것을 특징으로 하는 미세패턴형성을 위한 사진식각방법.
- 제 1 항에 있어서, 상기 단계중 레지스트는 포지티브형 레지스트 중 어느 하나인 것을 특징으로하는 미세패턴형성을 위한 사진식각방법.
- 제 1 항 또는 제 4 항에 있어서, UV 레지스트 재료는 고무수지 비율이 PAC 비율보다 2~3배 높은 레지스트인 것을 특징으로 하는 미세패턴형성을 위한 사진식각방법.
- 제 1 항 또는 제 4 항에 있어서, DUV 레지스트 재료는 DUV광에 대해 흡수도가 10% 이상으로 높은 Novolac 계통의 흡수력이 있는 레지스트인 것을 특징으로 하는 미세패턴형성을 위한 사진식각방법.
