    • A semiconductor wafer, having a relatively wide power supply line and ground line, and which can also prevent short-circuiting between these lines. Multiple integrated circuit formation regions, whereon integrated circuits have been formed, are disposed on a semiconductor wafer. A silicon oxide film is formed on a silicon substrate, and a ground line conductor is formed on the silicon oxide film. This ground line conductor is extended over scribe lines. A layer insulation film composed of silicon oxide film is deposited on the silicon oxide film with the ground line conductor interposed therebetween, and a power supply line conductor is formed on the layer insulation film to overlap the ground line conductor. The power supply line conductor is extended over scribe lines. In the integrated circuit formation regions, a power supply pad and the power supply line conductor are electrically connected. A ground pad and the ground line conductor are also electrically connected.

    • The present invention is aimed at avoiding noise generation accompanying switching actions in booster circuits for a load such as an air-bag driving circuit. In an air-bag driving circuit, which is designed to actuate an igniting transistor 13 in response to output of a collision detecting signal from a collision detector 7 for detecting a collision condition of a vehicle so as to supply an igniting current to a squib 11 based on a voltage boosted by booster circuits 4 and 5, the boosting operation of the booster circuits 4 and 5 is inhibited while the collision detecting signal is absent and started when the collision detecting signal is output from the collision detector 7.
    • 本发明旨在避免伴随诸如气囊驱动电路的负载的升压电路中的切换动作的噪声产生。 在气囊驱动电路中,其被设计成响应来自碰撞检测器7的碰撞检测信号的输出来致动点火晶体管13,用于检测车辆的碰撞状况,以便向点火器11提供点火电流 基于由升压电路4和5升压的电压,当碰撞检测信号从碰撞检测器7输出时,不存在冲突检测信号并开始升压电路4和5的升压操作。
