An atomic clock is used in conjunction with the GNSS receiver and the inertial sensors, creating a more capable inertial navigation system (INS). The system is composed of a GNSS receiver, an accurate clock, and a mechanism for measuring relative pose changes. The system being presented utilizes an inertial measurement unit (IMU) to provide the relative pose changes, but other mechanisms can be used—like visual and ladar odometry. The GNSS receiver measures the pseudo-ranges to the GNSS satellites in the field of view. These measurements are “time tagged” with the accuracy of the atomic clock. The relative motion between the pseudo-ranges is measured using the IMU. Finally, the lock is achieved by filtering these measurements. The filtering mechanism can vary, from the traditional Kalman Filters to other mechanisms that attempt to minimize the mean square error.

The top ends of polysilicon gate electrodes with different gate lengths are formed so as to be equally high and lower than the top end of the side wall. A metal film is formed so as to cover the polysilicon gate electrodes, followed by silicidation by thermal treatment. Since the top ends of the polysilicon gate electrodes are formed lower than the top end of the side wall, a silicon side reaction is not accelerated even in the case of a fine gate length, and proceeds in a one-dimensional manner. As a result, full-silicide gate electrodes having a uniform metal composition ratio can be stably formed even using the polysilicon gates with different gate lengths.

A transformer section transforms a primary voltage and outputs secondary voltage. A control section inputs a first signal indicating a state of electricity supply of a primary power source through an in-vehicle network. The transformer section outputs a second signal indicating a state of electricity supply of the transformer section. When the input of the first signal is disrupted, the control section limits the driving electricity supplied to the steering motor based on at least one of a value of the secondary voltage and the electricity supply state of the transformer section indicated by the second signal. Accordingly, driving electricity is stably supplied with the steering motor with a simple configuration even if the input of the first signal is disrupted due to a failure in the in-vehicle network.
