摘要： Provided is an adhesive composition for multilayer semiconductors. The adhesive composition gives, when applied and dried by heating, an adhesive layer that has approximately no adhesiveness at a temperature lower than 50° C., but, when heated at such a temperature as to less cause damage to semiconductor chips, offers adhesiveness and is rapidly cured thereafter. This adhesive composition for multilayer semiconductors includes a polymerizable compound (A), at least one of a cationic-polymerization initiator (B1) and an anionic-polymerization initiator (B2), and a solvent (C). The polymerizable compound (A) contains 80% by weight or more of an epoxide having a softening point or melting point of 50° C. or higher. The cationic-polymerization initiator (B1) gives a composition having a thermal curing time of 3.5 minutes or longer at 130° C., where the composition contains 1 part by weight of the cationic-polymerization initiator (B1) and 100 parts by weight of 3,4-epoxycyclohexylmethyl (3,4-epoxy)cyclohexanecarboxylate. The anionic-polymerization initiator (B2) gives a composition having a thermal curing time of 3.5 minutes or longer at 130° C., where the composition contains 1 part by weight of the anionic-polymerization initiator (B2) and 100 parts by weight of bisphenol-A diglycidyl ether.
