  • Patent number: 7936569
    Abstract: In a hybrid integrated circuit device that is a circuit device of the present invention, a conductive pattern including pads is formed on a surface of a substrate. A first pad is formed to be relatively large since a heat sink is mounted thereon. A second pad is a small pad to which a chip component or a small signal transistor is fixed. In the present invention, a plated film made of nickel is formed on a surface of the first pad. Therefore, the first pad and a solder never come into contact with each other. Thus, a Cu/Sn alloy layer having poor soldering properties is not generated but a Ni/Sn alloy layer having excellent soldering properties is generated. Consequently, occurrence of sink in the melted solder is suppressed.

  • Patent number: 7884008
    Abstract: A method of forming a semiconductor device including a semiconductor substrate with circuit elements and electrode pads formed on one surface. This surface is covered by a dielectric layer with openings above the electrode pads. A metal layer is deposited on the dielectric layer and patterned to form a conductive pattern with traces leading to the electrode pads. A protective layer having openings exposing part of the conductive pattern is formed. Each opening is covered by an electrode such as a solder bump, which is electrically connected through the conductive pattern to one of the electrode pads. The method enables the thickness of the protective layer, which may function as a package of the semiconductor device, to be reduced. The protective layer may be formed from a photosensitive material, simplifying the formation of the openings for the electrodes.

  • Patent number: 7884454
    Abstract: A semiconductor package assembly may include a lead frame having a die bonding pad and plurality of leads coupled to the first die bonding pad. A vertical semiconductor device may be bonded to the die bonding pad. The device may have a conductive pad electrically connected to one lead through a first bond wire. An electrically isolated conductive trace may be formed from a layer of conductive material of the first semiconductor device. The conductive trace provides an electrically conductive path between the first bond wire and a second bond wire. The conductive path may either pass underneath a third bond wire thereby avoiding the third bond wire crossing another bond wire, or the conductive path may result in a reduced length for the first and second bond wires that is less than a predetermined maximum length.
