Abstract: In connection with a semiconductor device in which a conductive member is coupled to the surface of a bonding pad exposed from an opening formed in a passivation film, there is provided a technique able to suppress the occurrence of a crack in the passivation film. A second planar distance between a first end of an electrode layer and a first end of a pad is greater than a first planar distance between the first end of the electrode layer and a first end of an opening. Since the second planar distance between the first end of the electrode layer and the first end of the pad is long, even when a coupled position of wire is deviated to the first end side of the electrode layer, stress caused by coupling of the wire to a stepped portion of the electrode layer can be prevented from being transmitted to the first end portion of the pad.

Abstract: A high-precision A/D conversion is realized while the number of external terminals used for an A/D converter is reduced. At the time of sampling, first to fifth switches are turned on and a sixth switch is turned off. Since a first resistor is set to a resistance value optimum for sampling, an impedance in the direction from a node A to the left side and an impedance in the direction from a node B to the left side almost match, and a large noise-cancelling effect is obtained. At the time of successive approximation, the first, second, third, and fifth switches are turned off and the fourth and sixth switches are turned on. Since a second resistor is set to a resistance value optimum for the successive approximation, the impedance in the direction from the node A to the left side and the impedance in the direction from the node B to the left side almost match, and a large noise-cancelling effect is obtained also at the time of successive approximation.

Each PDU has a motor, at least one driver roller element coupled to said motor, a light source, a light detector, and a processor. The light detector of each PDU is configured to receive and process an incoming coded light signal from a wireless remote control handset. The PDU's processor determines whether the received coded light signal is a valid command signal and, if so, provides a command information signal to the controller via the wired network. The controller decodes the command information signal and, in view of its knowledge of container locations, various switch settings and other status information, the controller then sends the appropriate control signals to turn on the required PDUs in response thereto.
