发明名称 Interconnection structure of electronic parts comprising solder bumps with metal core members
摘要 An interconnection structure is provided which is simple in structure and is easily manufactured and in which stress generated in solder bumps is minimized. Pads 5 of a semiconductor chip 1 and pads 6 of a substrate 2 are connected to each other by solder bumps 3. The solder bumps are hourglass-shaped. Metal core members 4 are provided in the solder bumps 3, respectively. The core member 4 is constituted with a circular bottom portion 41 and a circular pin portion 42. The core member 4 is soldered to the pad 5 of the semiconductor chip 1 by solder 7. <IMAGE>
