  • Patent number: 8084826
    Abstract: An element larger than silicon is ion-implanted to a contact liner in an N-channel region to break constituent atoms of the contact liner in the N-channel region. An element larger than silicon is ion-implanted to the contact liner in a P-channel region to break constituent atoms of the contact liner, oxygen or the like is ion-implanted.

  • Publication number: 20070277509
    Abstract: Decreases in the volume of intake air to an engine in response to environmental changes results in an increase in amount of PM emissions. In view of this situation, a correction coefficient of fuel supply interval is calculated based on the variation in amount of PM emissions to adjust a reference fuel supply interval in order to determine an target fuel supply interval. By adjusting the fuel supply interval, a fuel supply amount appropriate to the variation in amount of PM emissions, thereby preventing clogging of the injection hole of a supplemental fuel valve, while maintaining fuel economy.

  • Patent number: 7276769
    Abstract: In a semiconductor integrated circuit device, semiconductor elements formed in active regions included in a first element formation portion (stress transition region) in a peripheral circuit formation portion are not electrically driven, while only semiconductor elements of a second element formation portion (steady stress region) are electrically driven. Therefore, the second element formation portion in the peripheral circuit formation portion is located away from an outer STI region so as to be hardly affected by compressive stress.
