PURPOSE: An adhesive tape with a magnet-adhesive layer is provided to reduce process cost, to simplify a semiconductor package process, and to improve workability. CONSTITUTION: An adhesive tape comprises an adhesive layer formed on one side of the substrate film and a magnet-attached layer(2) spread on the other side of the substrate layer. The adhesive layer comprises 100.0 parts by weight of an acrylic copolymer, 0.01-30 parts by weight of hardener, 0.05-30 parts by weight of an energy-curable acrylic oligomer, and 0.0-125 parts by weight of a photoinitiator. The molecular weight of the acrylic copolymer is 400,000-4,000,000. The adhesion of the adhesive layer is 1-350 gf/inch. |
