  • Patent number: 9324661
    Abstract: An aligning guide, a semiconductor package comprising an aligning guide, and a method of manufacturing a semiconductor package comprising an aligning guide are provided. The semiconductor package may comprise a circuit board and an aligning guide mounted on the circuit board. The aligning guide may have a plurality of stepped portions. A plurality of semiconductor chips may be stacked on the circuit board and engage with the stepped portions of the aligning guide. According to the disclosed semiconductor package, a large number of semiconductor chips may be stacked with high accuracy and sufficient margin. Therefore, the rate of failure and defects in the chip stacking process may be reduced and the reliability and stability of the semiconductor package may be enhanced.

  • Publication number: 20130056448
    Abstract: A wire bonding system of a semiconductor package comprising a wire feeding device for positioning a wire at a ball formation position, a laser beam generation unit for generating a carbon dioxide laser beam, and a laser beam guiding unit for directing the laser beam at the ball formation position to form a ball at the wire. Accordingly, moldability and producibility of the ball formed on the wire may be improved. Also, electrical properties at a section of the wire are modified so as to minimize a loop height of the wire.
