A voice processing system comprises a processing device that processes and receives a stream of voice input as a user is speaking. In one embodiment, a maximum price is specified. The system compares the estimated position to a desired position along a planned path of a borehole. The semiconductor integrated circuit device includes a current control device connected between the logic gate and the first potential point andor between the logic gate and the second potential point for controlling a value of a current flowing in the logic gate depending on an operating state of the logic gate. Thereafter, a first conductive layer and a second conductive layer are electroplated respectively over the first pads and the second pads.
