Abstract
In this semiconductor chip, a table electrodeis interposed between a bump electrodeand an electrode pad. The table electrodeis formed by forming a plurality of coreshaving a smaller Young's modulus than the bump electrode, on the electrode pad, and then covering the surfaces of the coreswith a conductive electrode. When the semiconductor chipis flip-chip mounted, the bump electrodeis plastically deformed and the table electrodeis elastically deformed appropriately, thereby obtaining a good conductive state.
