Abstract:
A semiconductor device comprising:a semiconductor chip bonded to a central portion on one surface of a heat sink by metal bonding; a stiffener glued to one surface of said heat sink in such a way as to surround said semiconductor chip; solder bumps formed on one surface of said stiffener; connection means for electrically connecting said solder bumps and electrodes of said semiconductor chip; and a sealing resin for sealing said semiconductor chip, wherein said heat sink is formed of a material having a thermal expansion coefficient close to a thermal expansion coefficient of said semiconductor chip, wherein said stiffener and said heat sink are glued together with an adhesive with an elastic modulus lower than an elastic modulus of said sealing resin, and wherein the elastic modulus of said adhesive is 50 MPa or less.
