ABSTRACT:
A composition comprising an epoxy resin and a curing agent is blended with a thermoplastic resin impregnated with an organic silicon compound to provide an epoxy resin composition which cures into products having improved adhesion and thermal impact and is suitable for encapsulating semiconductor devices.
The impregnated thermoplastic resin is formed by swelling the thermoplastic resin with a solvent and impregnating the swollen thermoplastic resin with the organic silicon compound.
