  • Patent number: 8441457
    Abstract: A sensor device includes: one or more sensor elements each including first and second diode elements connected in series and a sensor driving section. The cathode of the second diode element is connected to the anode of the first diode element. The sensor driving section controls on-off state of the first diode element through changing a gate voltage under a fixed cathode voltage, and controls on-off state of the second diode element through changing a gate voltage under a fixed anode voltage. The sensor driving section drives the second diode element, maintaining a relationship of Vg2(off)<Vp2<Vg2(on), and, in off-to-on transition of the second diode element, overdrives the second diode element through temporarily applying a gate voltage Vg2(od) to the gate electrode, maintaining a relationship of Vg2(on)<Vg2(od). Vp2, Vg2(on) and Vg2(off) are the anode voltage, a on-state gate voltage and a off-state gate voltage of the second diode element, respectively.

  • Patent number: 8089162
    Abstract: In a pad forming region electrically connecting an element forming region to the outside, in which a low dielectric constant insulating film is formed in association with in the element forming region, a Cu film serving as a via formed in the low dielectric constant insulating film in the pad forming region is disposed in higher density than that of a Cu film serving as a via in the element forming region. Hereby, when an internal stress occurs, the stress is prevented from disproportionately concentrating on the via, and deterioration of a function of a wiring caused thereby can be avoided.
