Patent ID: 6919646

Claim:
A semiconductor device comprising: a first constituent member having an electrode formed thereon; a second constituent member having an electrode formed thereon; and a mixture of a thermoplastic resin and a thermosetting resin, wherein said mixture intervenes with said first constituent member and said second constituent member in such a manner that the electrode of said first constituent member and the electrode of the second constituent member are in electrical contact with each other without intervention of said mixture therebetween, wherein a melting temperature of said thermoplastic resin is greater than a glass transition temperature of said thermosetting resin, and wherein X·E 1 ·α 1 <(1−X)·E 2 ·α 2 holds, where E 1 is a modulus of elasticity of said thermoplastic resin, α 1 is a coefficient of thermal expansion of said thermoplastic resin, E 2 is a modulus of elasticity of said thermosetting resin, α 2 is a coefficient of thermal expansion of said thermosetting resin, and X is a content by percentage of said thermoplastic resin in said mixture and 0<X<1.
