Abstract:
An electronic device includes a chip with an integrated electronic component and a terminal made of a first metal material. The device further includes a lead made of a second metal material different from the first metal material. A bonding wire made of a selected one of the first and second metal materials has opposite ends coupled with the terminal and the lead. An interface element having a first layer made of a selected one of the first and second metal materials and a second layer made of an unselected one of the first and second metal materials has the first layer coupled with the bonding wire and the second layer coupled with a component, wherein the component is ether the terminal or the lead.
