| 摘要 |
In the semiconductor device manufactured by the manufacturing method of the present invention, the tungsten layer resistant to an impulsive force is formed without the oxide film layer existing below the second pad. Hence, if an external force is applied to the second pad through an opening upon bonding or the like, cracks are hard to occur. Accordingly, it is possible to provide a semiconductor device high in mechanical strength and reliability and a method of manufacturing.
