Abstract

The acrylic copolymers with variation in side chain were synthesized based on molecular design. Wettability and adhesion properties on the wafer surface were investigated for these acrylic copolymer pressure sensitive adhesives. Three-dimensional networks of linear acrylic copolymers were produced with epoxy-type Tetra-DX cross-linking agent. The effect of cross-linking on adhesion characteristics was investigated. The side chain of acrylic copolymer played more important role in wettability than the interfacial interaction. As the degree of cross-linking increased, both probe tack and peel strength decreased. Also, heat resistance measured by SAFT increased with cross-linking; however, it showed the deterioration when excess cross-linking agent was added.

분자설계를 통하여 측쇄를 변화시킨 아크릴공중합체를 합성하여 아크릴공중합체 점착제와 초박형웨이퍼와의 젖음성 및 점착물성을 조사하였다. 선형 아크릴공중합체를 에폭시계 Tetra-DX 가교제와 반응시켜 3차원 망상구조를 형성하고 가교의 영향을 조사하였다. 계면상호작용보다는 아크릴공중합체의 측쇄변화가 젖음성에 더 큰 영향을 미쳤다. 가교도가 증가할수록 probe tack, peel strength가 감소하는 경향을 나타냈다. 가교에 의해 SAFT 내열성이 증가하였지만 가교제의 함량이 증가하면 오히려 SAFT 내열성이 감소하였다.
