Abstract:
1. A thermosetting die-bonding film that is used in manufacturing a semiconductor device, comprising at least an epoxy resin, a phenol resin, an acrylic copolymer, and a filler, wherein the epoxy resin, phenol resin, and acrylic copolymer are characterized by a ratio X/Y of 1 to 5 when X represents a total weight of the epoxy resin and the phenol resin and where Y represents a weight of the acrylic copolymer, the thermosetting die-bonding film is further characterized as having a melt viscosity at 120 to 130° C. in the range of 500 to 3500 Pa·s, the acrylic copolymer comprises 10 to 60% by weight of butyl acrylate and 40 to 90% by weight of ethyl acrylate, and the filler is present in an amount of 18 parts by weight to 80 parts by weight relative to 100 parts of a total weight of the epoxy resin, the phenol resin and the acrylic copolymer.
