Abstract: A semiconductor device has a semiconductor chip fixedly mounted on an island and a bonding wire connecting a bonding pad on the semiconductor chip to a lead terminal whose end is positioned near the island. The semiconductor chip and the bonding wire are encased by a molded resin. The bonding wire includes a first extension ascending substantially vertically from the bonding pad, a second extension extending substantially horizontally from the first extension, and a third extension descending substantially vertically from the second extension. A bend between the second and third extensions is disposed outwardly of an end of the semiconductor chip.
