PURPOSE:To prevent displacement of a chip by forming a slightly larger recess than the chip at the center of an island. CONSTITUTION:A recess being slightly larger than a semiconductor chip 5 longitudinally and laterally and having infinitesimal size is formed at the center of an island 6. A gold plate 7 is coated on the recess, and molten at high temperature, and the semiconductor chip 5 is melt-stuck thereto. |
