Semiconductor device with improved heat dissipation, and a method of making semiconductor device

摘要

A semiconductor device includes a semiconductor chip, a heat dissipation member for dissipating heat generated by the semiconductor chip, and a coupling member which thermally couples the semiconductor chip to the heat dissipation member, wherein the coupling member is made of metal and deformable to absorb a stress generated between the semiconductor chip and the heat dissipation member, the coupling member and the semiconductor chip being joined through metal-metal bonding.
