Abstract
A semiconductor device includes a bonding-structure for electrically and mechanically bonding a solder ball to the electrode pad. The bonding-structure includes flexible arms that are connected to a common supporting layer that allows a relative displacement of the solder ball in relation to the semiconductor chip. The arms extending in one direction are supported by one supporting layer and the arms extending in an opposite direction are supported by another supporting layer.
