To provide a semiconductor device production method capable of solving the problem of the latent period of time in which polishing is hardly performed immediately after a polishing start. The method includes applying friction braking and powertrain braking to the vehicle. At the restricting position, the restriction portion restricts an inclination of the FOUP on the bottom portion. Any one of the gray scale voltage out of the plurality of gray scale voltages having a selected polarity is selected based on digital video data, with or without inversion of a polarity of gray scale voltages. The array includes a number of driven radiating elements that are spatially arranged having a pivoting actuator so as to provide a controlled variation of the antenna array’s radiation pattern.
