Abstract
A semiconductor chip has such a structure as to have first connection electrodes formed at its upper circumferential edge portion and each exposed over a corresponding opening in a protective layer. An insulating layer is formed on the semiconductor chip except at each opening in the protective layer. Interconnect lines of an electroless-plated layer are formed on the first connection electrode. Solder bumps are formed on second connection electrodes formed together with the interconnect lines.
