  • Patent number: 7834466
    Abstract: A structure includes a semiconductor die that has an arrangement of die pads on a surface of the semiconductor die. A first row of die pads consists of a first group of four die pads and run in a first direction. A second row of die pads are adjacent to the first row and consist of a second group of four die pads running in the first direction. The second row begins at a first offset in the first direction from where the first row begins. A third row of die pads are adjacent to the second row and comprise a third group of four die pads that run in the first direction. The third row begins at a second offset in the first direction from where the second row begins. This allows for relatively easy access to all of the die pads.

  • Patent number: 7833831
    Abstract: An electronic component is equipped with electrode protrusions that make it possible to mount the electronic component without covering connection pads of a circuit board with solder and to dispose the connection pads of the circuit board with a narrow pitch while preventing electrical shorting of the connection electrodes during mounting. A method of manufacturing an electronic component equipped with connection electrodes, where electrode protrusions are covered with solder, includes a step of heating a solder sheet to a semi-molten state and pressing the electronic component onto the solder sheet to place the electrode protrusions in contact with the solder sheet and a step of retracting the electronic component from a position where the electrode protrusions contact the solder sheet to transfer solder onto outside surfaces of the electrode protrusions that contacted the solder sheet.

  • Patent number: 7821096
    Abstract: A semiconductor integrated circuit having a diode element includes a diffusion layer which constitutes the anode and two diffusion layers which are provided on the left and right sides of the anode and which constitute the cathode, such that the anode and the cathode constitute the diode. A well contact is provided to surround both the diffusion layers of the anode and cathode. Distance tS between a longer side of the well contact and the diffusion layers of the cathode is shorter, while distance tL between a shorter side of the well contact and the diffusion layers of the anode and cathode is longer (tL>tS). Accordingly, the resistance value between the diffusion layer of the anode and the shorter side of the well contact is larger, so that the current from the diffusion layer of the anode is unlikely to flow toward the shorter side of the well contact.

  • Patent number: 7816183
    Abstract: In the multiple-layered semiconductor device and the method for manufacturing thereof according to the present invention, the resin is formed on the substrate around the semiconductor device, on which the semiconductor device is installed in the first semiconductor package. Therefore, a generation of a warpage of substrate is inhibited in the first semiconductor package. And since the first semiconductor package is stacked to and coupled to the second semiconductor package via the electric conductors that extend from the back surface of the second semiconductor package to the coupling lands on the substrate penetrating through the resin, a defective situation such as a coupling defective in the bump junction can be avoided when the junction of the second semiconductor package via the electric conductor is formed. Therefore, a considerably improved coupling reliability in the multiple-layered semiconductor device can be achieved.
