Patent ID: 8008124

Claim:
An adhesive film for a semiconductor to be used for stacking semiconductor chips in two or more layers, comprising: (A) an ester (meth)acrylate copolymer; and (B) a thermoplastic resin other than said ester (meth)acrylate copolymer; said adhesive film for a semiconductor have a shearing strain γ satisfying the following formula (1) for two hours from 10 minutes after starting measurement, in which the shearing strain γ represents an amount of shearing strain produced upon undergoing a shearing stress of 3000 Pa at a frequency of 1 Hz and a temperature of 175° C., on parallel plates of 20 mm in diameter: 0.10≦γ≦0.30 (1) wherein the adhesive film is substantially free from a thermosetting resin.
