Abstract:
1. A stacked package for an electronic device, the stacked package comprising: a first semiconductor package including a first package substrate, a first semiconductor chip and a first molding member, the first package substrate having first pads and second pads being disposed on an upper surface of the first package substrate, the first semiconductor chip arranged on the upper surface of the first package substrate, and the first molding member formed on the first package substrate to cover the first semiconductor chip; a second semiconductor package including a second package substrate, a second semiconductor chip, conductive wires and a second molding member, the second package substrate disposed over the first package substrate and having third pads and fourth pads being disposed on an upper surface of the second package substrate, one of the third pads being disposed directly above one of the first pads, the second semiconductor chip arranged on the upper surface of the second package substrate, the conductive wires configured to electrically connect the second semiconductor chip and the second package substrate, and the second molding member formed on the second package substrate to cover the conductive wires and the second semiconductor chip and covered by the first molding member a conductive ball electrically connecting one of the first pads and one of the third pads directly above it and supporting the second semiconductor package above the first semiconductor package; and a conductive wire having a diameter less than the conductive ball and electrically connecting one of the second pads and one of the fourth pads, the conductive wire being covered by the first molding member, wherein a first signal having a first transmission speed is transmitted through the conductive ball and a second signal having a second transmission speed slower than the first transmission speed is transmitted through the conductive wire.
