Claims (1)
- 반도체 웨이퍼의 주변노광방법에 있어서, 빛을 차단할 수 있는 광차단부와 빛이 통과되는 광통과부가 형성된 주변노광용 마스크를 포토레지스트가 도포된 웨이퍼와 일정거리를 두고 설치한 다음 상기 광차단부와 웨이퍼의 소자형성영역이 빛의 방향에 대하여 일치되도록 얼라인 하는 얼라인공정을 수행하는 단계와, 상기와 같이 설치된 웨이퍼의 반대쪽에서 주보냈노광용 마스크에 빛을 주사하여 광통과부를 통하여 통과되는 빛이 웨이퍼의 에지부분에 도포되어 있는 포토레지스트를 노광시키는 빛주사공정을 수행하는 단계를 순차적으로 실시하는 것을 특징으로 하는 반도체 웨이퍼의 주변노광방법.
