  • Publication number: 20120261835
    Abstract: The present invention provides a technique for improving the reliability of a semiconductor device where spreading of cracking that occurs at the time of dicing to a seal ring can be restricted even in a semiconductor device with a low-k film used as an interlayer insulating film. Dummy vias are formed in each layer on a dicing region side. The dummy vias are formed at the same intervals in a matrix as viewed in a top view. Even in the case where cracking occurs at the time of dicing, the cracking can be prevented from spreading to a seal ring by the dummy vias. As a result, resistance to moisture absorbed in a circuit formation region can be improved, and deterioration in reliability can be prevented.

  • Publication number: 20120263053
    Abstract: There is provided a sensor network information collection mechanism in which, after a UE has decided to become part of an information collecting operation for collecting information from a local sensor network, a signaling transmitted from a managing node of a local sensor network is received and processed. A communication network control element is informed about the willingness to become an information collector by sending a report message comprising measurement results derived from the signaling received from the managing node of the local sensor network. When receiving a gateway allocation message indicating that the UE is determined to be a gateway element to the local sensor network, the information collecting operation is started wherein sensor nodes of the local sensor network are woke up, and a traffic flow direction in the local sensor network is set in accordance with the managing node identity to which the UE is accessed.

  • Publication number: 20120262223
    Abstract: A semiconductor device includes a signal output unit, and a decision unit. The signal output unit includes m (?2) pieces of fuses, a NAND gate, resistance elements, and an output terminal. The decision unit decides whether n or more pieces (m?n?2) of fuses are disconnected out of the m pieces of fuses included in the signal output unit, and outputs the result of a decision. When m=n=2, the decision unit is constituted of a NOR gate having two input terminals connected to a respective end of the fuses. Thus, a H-level potential signal is output at an output terminal of the NOR gate when the decision result is affirmative. On the other hand, when the decision result is negative, a L-level potential signal is output at the output terminal.

  • Publication number: 20120256816
    Abstract: In conventional liquid crystal display controllers, the display is reduced in the stand-by state but the liquid crystal display duty is not changed, i.e., even the common electrodes of the rows that are not producing display are scanned, and the consumption of electric power is not decreased to a sufficient degree in the stand-by state. A liquid crystal display controller includes a drive duty selection register capable of being rewritten by a microprocessor, and a drive bias selection register. When the display is changed from the whole display on a liquid crystal display panel to a partial display on part of the rows only, the preset values of the drive duty selection register and of the drive bias selection register are changed, so that the display is selectively produced on a portion of the liquid crystal display panel at a low voltage with a low-duty drive.
