Abstract: PROBLEM TO BE SOLVED: To improve workability, adhesive property, insulation reliability and durability by a method wherein one or more kinds of resin and thermosetting resin, having an amide group and/or an imide group, are contained as the essential component of an adhesive material composition. SOLUTION: A bonding agent solution is formed by dimer acid polyamide, epoxy resin, 4,4'-diaminodiphenylsulfone, phenol resin and triphenylphosphine, in the prescribed mixing ratio, and ethanol/toluene mixed solution. This bonding agent solution is applied to a polyethylene terephthalate film and the applied solution is dried up. On the other hand, an adhesive layer is formed in the same manner as above excepting the use of polyethylene terephthalate and silicone mold releasing agent having low stripping force. Then, an adhesive sheet for semiconductor device is formed by laminating two sheets of the above- mentioned film, formed by putting adhesive surfaces together, and a pure copper plate, having an adhesive layer, is obtained by laminating the pure copper plates.

Abstract: PROBLEM TO BE SOLVED: To improve the adhesive property, the chemical resistance and the insulating characteristics at a high temperature by a method wherein a thermoplastic resin, an epoxy resin, silica particles and a silane coupling agent are contained as essential components in an adhesive layer of the tape with adhesive for TAB. SOLUTION: A thermoplastic resin, an epoxy resin, silica particles and silane coupling are contained as essential components in an adhesive layer 2 of the tape with adhesive for TAB composed of a laminated body having a plastic organic insulating film 1, an adhesive layer 2 and a protective film layer. The silica particles are in the mean particle diameter not exceeding about 10μm and the maximum particle diameter not exceeding about 20μm while the blending ratio thereof about 5-70wt.% of the whole adhesive layer. Furthermore, the surface of the silica particles is to be previously processed with the silane coupling agent whose additive amount is to be about 0.5-10wt.% to the 100wt.% of the silica particles.
