Title:
CIRCUIT CONNECTION MATERIAL, CONNECTION METHOD USING SAME, AND CONNECTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/042632
Kind Code:
A1
Abstract:
Provided is a circuit connection material that, while suppressing fluctuations in the resistance value between circuit electrodes when subjected to high-temperature, high-humidity processing, is able to evince superior connection reliability by increasing the adhesion with the interface to a silicon nitride film. By being interposed between a pair of circuit members disposed in a manner so that the circuit electrodes face each other, the circuit connection material electrically and mechanically connects the opposing circuit members. The circuit connection material contains: (1) a polyfunctional (meth)acrylate monomer; (2) a curing agent that generates free radicals by means of heat or light; and (3) a reactive acrylic polymer that has an ethylenic unsaturated group in a side chain and has 1000-12000 double bond equivalents.
