Abstract:
In this semiconductor chip 3, a table electrode 13 is interposed between a bump electrode 14 and an electrode pad 6. The table electrode 13 is formed by forming a plurality of cores 15 having a smaller Young's modulus than the bump electrode 14, on the electrode pad 6, and then covering the surfaces of the cores 15 with a conductive electrode 16. When the semiconductor chip 3 is flip-chip mounted, the bump electrode 14 is plastically deformed and the table electrode 13 is elastically deformed appropriately, thereby obtaining a good conductive state.
