  • Electronic device with bimetallic interface element for wire bonding
    Patent number: 9184150
    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.
    Type: Grant

  • Electronic device and method for connecting a die to a connection terminal
    Patent number: 8513811
    Abstract: An electronic device including a die-pad area, a die fixed to the die-pad area, a connection terminal, and a ribbon of conductive material. The ribbon is electrically connected to the die and to the connection terminal, and has a prevalent dimension along a first axis, a width, measured along a second axis, which is transverse to the first axis, and a thickness, which is negligible with respect to the width; the ribbon moreover has a cross section that defines a concave geometrical shape.
