Patent ID: 8293847

Claim:
A film-like adhesive used for bonding a semiconductor element to an adherend, wherein the film-like adhesive has an adhesive layer comprising a polyurethaneimide-polyurethaneamideimide resin, and wherein the polyurethaneimide-polyurethaneamideimide resin comprises a polymer having: (1) a partial structure represented by a formula (1a) shown below: [wherein, R 1a represents a bivalent organic group comprising either an aromatic ring, or a straight-chain, branched or cyclic aliphatic hydrocarbon, R 2a represents a bivalent organic group with a molecular weight within a range from 100 to 10,000, R 3a represents a tetravalent organic group containing a total number of carbon atoms of 4 or greater, and n 1a represents an integer from 1 to 100], and (2) a partial structure represented by a formula (1b) shown below: [wherein, R 1b represents a bivalent organic group containing either an aromatic ring, or a straight-chain, branched or cyclic aliphatic hydrocarbon, R 2b represents a bivalent organic group with a molecular weight within a range from 100 to 10,000, R 3b represents a trivalent organic group containing a total number of carbon atoms of 4 or greater, and n 1b represents an integer from 1 to 100].
