Patent abstract
A dicing die adhesive film for semiconductor of the present invention has a 3-layered structure including a first adhesive layer attached on the back of a semiconductor wafer; a second adhesive layer attached onto the first adhesive layer; and a dicing film attached onto the second adhesive layer, and therefore has an advantage that it can ensure reliability of the semiconductor packaging process since it may prevent the die-flying phenomenon and the poor pickup of the die in the dicing process and maintain a sufficient adhesive force between the die and the substrate upon die boding.
