IPC: H01L21/52
Filed: 1988-12-16
Abstract: PURPOSE:To relax a thermal stress caused by a difference in a coefficient of thermal expansion between a semiconductor integrated circuit chip and an island part and, at the same time, to secure a high heat-dissipating property by a method wherein the semiconductor integrated circuit chip and the island are bonded only partially by using a bonding material whose core part is constituted of a thin metal foil of a high heat-conducting property and whose outside is constituted of a solder. CONSTITUTION:In a semiconductor device where a semiconductor integrated circuit chip 1 and an island part 2 of a lead frame are bonded and fixed, the core part of a bonding material 4 is constituted of a metal foil 4a of a high heat-conducting property and both outside parts of the metal foil 4 are constituted of solders 4b; the semiconductor integrated circuit chip 1 and the island part 2 are bonded only partially. Thereby, a thermal stress caused by a difference in a coefficient of thermal expansion between the semiconductor integrated circuit chip and the island part can be reduced to a minimum; it is possible to use the island which has a high heat-conducting property by its effect but whose coefficient of thermal expansion is largely different from that of the semiconductor integrated circuit chip; a high heat-dissipating property can be obtained.
