Abstract

본 발명은 포토마스크기판 또는 반도체 웨이퍼의 세정방법 및 그 장치에 관한 것이다. H2SO4와 H2O2의 양액의 혼합에 의해 생성되는 혼합열을 반응촉진에 유효이용한다. 즉, H2SO4와 H2O2를 각각 다른 노즐로부터 토출시키고, 노즐의 가장 가까운 바로 아래의 혼합포인트에서 양액을 혼합하여, H2SO4-H2O2혼합액을 조제한다. 이 혼합액을 회전시킨 포토마스크기판의 중심 근방에 낙하시켜서, 원심력에 의해 기판면에 전개시킨다. H2SO4-H2O2의 유량비, 혼합포인트의 높이, 기판의 회전수를 제어함으로써, 기판면상의 혼합액의 온도분포를 최소로 억제하여 균일한 세정을 할 수 있다. 이로써, 전자선(電子線) 리소그라피 등에 사용되는 난용성의 클로로메틸스티렌계 레지스트재료 등의 웨트박리도 가능하게 된다.
