The present invention provides a semiconductor device excellent in the reliability of connection between the semiconductor device and a mounting board. The semiconductor device has external connecting terminals. Each of the external connecting terminals includes a Cu electrode, intermetallic compounds containing Cu, each formed over the Cu electrode, stopper portions which cover surfaces of the intermetallic compounds at intervals, and a solder alloy comprising Bi and an impurity containing Sn formed over the stopper portions and the intermetallic compounds. |
