ADHESIVE SHEET AND DICING/DIE-BONDING FILM

摘要

PROBLEM TO BE SOLVED: To provide an adhesive sheet which is highly reliable and excellent in the property of filling irregularities, and to provide a dicing/die-bonding film.SOLUTION: The adhesive sheet contains a spherical alumina filler and a resin component which contains a high molecular weight component (A) and a low molecular weight component (B). The content of the spherical alumina filler is 78-88 pts.wt. based on 100 pts.wt. of the adhesive sheet. The spherical alumina filler has an average particle diameter of 2-9 μm and a specific surface area of 0.8-8.0 m/g. The weight ratio represented by (the weight of the high molecular weight component (A))/(the total weight of the high molecular weight component (A) and the low molecular weight component (B)) is 0.03-0.25.
