  • Publication number: 20140186607
    Abstract: An adhesive film, an adhesive composition, and a semiconductor device wherein, in the adhesive film, a difference between a storage modulus (A) of the adhesive film after 4 cycles and a storage modulus (B) of the adhesive film after 1 cycle is about 3×106 dyne/cm2 or less, the storage modulus (A) of the adhesive film after 4 cycles is about 7×106 dyne/cm2 or less, and the storage modulus (B) of the adhesive film after 1 cycle is about 2×106 dyne/cm2 or more, when curing at 125° C. for 1 hour and then at 150° C. for 10 minutes is defined as 1 cycle.
