Provided are a film-like adhesive that can prevent the back surface of a semiconductor chip, the front surface of a substrate, or the front surface of a heat sink from being partially fractured by a filler; and a method for producing a semiconductor package using the film-like adhesive.
The film-like adhesive includes an epoxy resin (A), an epoxy resin curing agent (B), a phenoxy resin (C), and a heat-conductive filler material (D), in which the heat-conductive filler (D) has an average particle size of 0.1 to 10.0 μm, a compression ratio at break in a microcompression test of 5 to 50% of the average particle size of the sample, a fracture strength in a microcompression test of 0.01 to 2.0 GPa, and a thermal conductivity of 30 W/m·K or higher, the content of component (D) is 10 to 70 vol % with respect to the total amount of the components (A) to (D), and the thermal conductivity after thermal curing is 1.0 W/m·K or higher.
