Summary: | PURPOSE: To improve the heat dissipation efficiency and the maintainability in a semiconductor device adapted to be used for a so-called multi-chip module in which a semiconductor chip is placed on the upper part of a circuit board. CONSTITUTION: The semiconductor device comprises a circuit board 4 placed with a semiconductor chip 3 on the upper surface and formed with external connection pins 23 on the lower surface, a cap 5 formed integrally with a heat radiating fin part 12 and made of high heat conductive material for sealing the chip 3 by arranging on the upper surface of the board 4, a base member 6 engaged with the lower surface of the board 4, and a clamping mechanism 8 for fixing the cap 5 to the member 6. The cap 5 is brought into direct contact with the chip 3, and the cap 5 and the member 6 sandwich the board 4 thereby to seal the chip 3. |
