Abstract: PURPOSE: A radiation-releasable adhesive composition is provided to have enough decompressed adhesion and initial adhesion, and to be easily delaminated because adhesion is rapidly decreased when irradiating with radiation. CONSTITUTION: A radiation-releasable adhesive composition comprises: an adhesive resin polymerized of one or more acrylic monomers in chemical formula 1, and an acrylic monomer containing a hydroxy group, a diisocyanate compound; and an acrylic monomer containing hydroxy group. In the chemical formula 1, R1 is hydrogen or methyl, and R2 is C4-12 alkyl. The adhesive resin comprises 70-95 weight% of one or more acrylic monomers in chemical formula 1, and 5-30 weight% of the acrylic monomer containing the hydroxy group.

Abstract: 본발명은방사선박리형점착제조성물및 상기조성물을포함하는반도체웨이퍼가공용점착시트에관한것으로, 구체적으로는 (a)하기화학식 1로표시되는 1종또는그 이상의아크릴계단량체와히드록시기를함유한아크릴계단량체가중합되어이루어진점착수지, (b)디이소시아네이트화합물및 (c)히드록시기를함유한아크릴계단량체를포함하는점착제조성물및 상기조성물을이용한점착시트에관한것이다. 본발명의점착제조성물을사용하는경우방사선조사에의한경화반응에의해점착력이저감되어반도체웨이퍼로부터의박리가쉽고, 박리후 반도체웨이퍼에오염물이남지않으며, 초박형의웨이퍼제조공정용점착시트를경제적으로제조할수 있다는장점이있다. [화학식 1]상기화학식에서, R은수소또는메틸이며, R는탄소수 4 ~ 12의알킬이다.
