    • PURPOSE:To enhance a heat-dissipating property by a method wherein the edge of a shaft-shaped boss is fixed and bonded to the surface of a semiconductor chip via an adhesive, a heat-dissipating body is mounted on the semiconductor chip and the semiconductor chip is covered with a sealing agent. CONSTITUTION:A heat-dissipating body 10 is constituted of the following: a square-pillar shaft-shaped boss 11 on the surface pf a semiconductor chip 2; and two fins. The heat-dissipating body 10 is mounted on the chip 2 while the lower edge of the shaft-shaped boss is fixed and bonded to the surface of the chip 2 by using an adhesive 20. The mounting face between the lower- stage fins 12 and a circuit board 1 is filled with a sealing agent 6, and the semiconductor chip 2 is covered with the sealing agent 6. Thereby, heat of the chip 2 is conducted to the heat-dissipating body 10 and is released to the outside form the fins 12. That is to say, the heat-dissipating property of the semiconductor chip becomes good. Since the sealing agent 6 is filled into the mounting face between the fins 12 and the circuit board 1, a sealing moistureproof property becomes good.
