A semiconductor device includes a first terminal, a second terminal, and a plurality of third terminals on a substrate. Memory chips are stacked on the substrate in an offset manner. Each memory chip has first pads, second pads, and third pads thereon. A first bonding wire is electrically connected to the first terminal and physically connected to a first pad of each memory chip. A second bonding wire is electrically connected to the second terminal and physically connected to a second pad of each memory chip. A third bonding wire electrically connects one third terminal to a third pad on each memory chip. A fourth bonding wire is connected to the first bonding wire at a first pad on a first memory chip of the stack and another first pad on the first memory chip. The fourth bonding wire straddles over the second bonding wire and the third bonding wire.

Semiconductor device

According to one embodiment, a semiconductor device includes a first electrode, a second electrode, and a wire extending between the first electrode and the second electrode. The wire includes a first conductor in contact with the first electrode and the second electrode, and a second conductor that is provided inside the first conductor and has no contact with the first electrode and the second electrode.

Semiconductor device and wire bonding method

A semiconductor device includes a semiconductor chip having an electrode pad, a terminal having a terminal pad, and a bonding wire. The bonding wire includes a first end portion, a first bonded portion bonded to the electrode pad, a loop portion extending between the semiconductor chip and the terminal, and a second bonded portion bonded to the terminal pad. The second bonded portion is a wedge bonded portion comprising a second end portion of the bonding wire opposite to the first end portion. A length of the first bonded portion in the first direction is greater than a length of the second bonded portion in the first direction.

In a case where a cellular phone exists outside a WOS system service area, the cellular phone receives a not-connectable signal and an audio message from a mobile switching controller. The cellular phone conducts disconnection processing with the not-connectable signal as a turning point. Moreover, the cellular phone stores an extension number and converts a dedicated special number into an external number for retransmission, thus establishing connection to a PBX. After the reception of a connection-accepted signal and an automatic exchange answer message from the PBX, the cellular phone automatically transmits the stored extension number.

An elevator apparatus includes an electric motor for driving the elevator apparatus, an elevator cage adapted to be lifted or lowered by the electric motor, a brake device for holding and retaining an elevator driving system, including the electric motor, and a malfunction detecting device responsive to the application of a torque to a retainer section of the brake device during the lifting or lowering of the elevator cage.

Elevator apparatus

In a cage position detector for a hydraulic elevator, there is provided a detector for measuring the time duration of the power failure, when the power fails. An amount of sinkage of a cage during the power failure is obtained by the time duration of the power failure and an average sinkage amount per unit time provide in advance. A cage position, which has been detected just before the power failure, is corrected by the above obtained amount of sinkage of the cage. A cage position, from which the elevator is to reopen a normal operation for service after the recovery of power, is specified by the corrected cage position. According to the present invention, even though the cage sinks during the long power failure, it is prevented to lose the true present position of the cage, from which the elevator is to reopen the normal operation after the recovery of power.
