Abstract

본 발명은 에너지선의 조사 전에는 충분한 감압접착성과 초기접착성을 가지며, 조사 후에는 고무탄성을 유지하면서 접착력이 격감하고, 다이싱후의 확장공정에 있어서 칩 정렬성이 우수한 점착제조성물 및 그와 같은 점착제조성물을 이용한 점착시트, 특히 웨이퍼가공용 또는 표면 보호용 점착시트를 제공하는 것을 목적으로 한다.
아크릴계 공중합체 (A)와, 에너지선 중합성 우레탄아크릴레이트올리고머 (B)와, 분자내에 1개의 아크릴로일기 또는 메타아크릴로일기를 갖는 에너지선 중합선화합물 (C)로부터 얻어지는 것을 특징으로 하며, 필요에 따라 가소제 (D), 가교제 (E), 광중합개시제 (F)를 더 함유할 수 있다.
