Description
(b) 상기 반도체 웨이퍼의 회로면과는 반대측의 이면을 박형(薄型) 가공하는 공정,
(c) 상기 반도체 웨이퍼의 회로면과는 반대측의 이면 상에, 적어도 자외선 경화형 점착제층을 가지는 다이싱 테이프를 맞붙이는 공정,
(d) 상기 반도체 웨이퍼를, 상기 반도체 웨이퍼 회로면과 상기 플라즈마 폴리머 분리층 사이에서, 상기 접착제 층 및 서포트 부재로부터 박리하는 공정,
(e) 상기 반도체 웨이퍼 상의 상기 접착제의 잔사를, 유기용제를 이용하여 세정하는 공정, 및,
(f) 상기 반도체 웨이퍼를 절단하여 칩화하는 공정을 포함하는 반도체 웨이퍼의 다이싱 방법으로서,
