Abstract:
1. A dicing die-bonding film having a dicing film having a pressure-sensitive adhesive layer on a base and a die-bonding film provided on the pressure-sensitive adhesive layer, wherein the pressure-sensitive adhesive layer is formed from an acrylic polymer comprising acrylic ester A represented by CH the compounded ratio of the acrylic ester A and the acrylic ester B is 40 to 10 mol % of the acrylic ester B with respect to 60 to 90 mol % of the acrylic ester A, the compounded ratio of the hydroxyl group-containing monomer is in the range of 10 to 30 mol % with respect to 100 mol % of the total of the acrylic ester A and the acrylic ester B, the compounded ratio of the isocyanate compound is in the range of 70 to 90 mol % with respect to 100 mol % of the hydroxyl group-containing monomer, the pressure-sensitive adhesive layer is cured by ultraviolet ray irradiation, and the die-bonding film is formed from an epoxy resin and is laminated on the pressure-sensitive adhesive layer after the ultraviolet ray irradiation.
