  • Patent number: 9627348
    Abstract: Laser assisted bonding for semiconductor die interconnections is disclosed and may, for example, include forming flux on a circuit pattern on a circuit board, placing a semiconductor die on the circuit board where a bump on the semiconductor die contacts the flux, and reflowing the bump by directing a laser beam toward the semiconductor die. The laser beam may volatize the flux and make an electrical connection between the bump and the circuit pattern. A jig plate may be placed on the semiconductor die when the laser beam is directed toward the semiconductor die. Warpage may be reduced during heating or cooling of the semiconductor die by applying pressure to the jig plate. Jig bars may extend outward from the jig plate and may be in contact with the circuit board during the application of pressure to the jig plate. The jig plate may comprise one or more of: silicon, silicon carbide, and glass.

  • Patent number: 7030508
    Abstract: Disclosed is a substrate for semiconductor package and a wire bonding method using thereof. The substrate is provided with at least one reference mark on its surface to check a loading position and a shift state of a solder mask. The reference mark is composed of a combination of a reference pattern and a solder mask opening and is positioned in any location on an outer peripheral edge of a die attachment region. The reference mark may take various shapes. A method for checking a solder mask shift using the reference mark includes comparing a design value of the reference pattern and the solder mask opening with the reference pattern and the solder mask opening, which are formed in an actual material. After the solder mask shift is calculated, a wire bonding coordinate is newly constructed in consideration of the solder mask shift. This minimizes the wire bonding error.
