Abstract: In a semiconductor device with multiple wiring layers, to connect a conductive line in a lower wiring layer to a conductive line in an upper wiring layer, two conductive members are formed in the space between the upper and lower conductive layers, one conductive member in contact with each conductive line. The two conductive members meet in the space between the two conductive layers to form an electrical path between the two conductive lines. One or both of the conductive members may have a rectangular bar shape extending lengthwise along the conductive line with which it makes contact. The conductive members can have a reduced height and enlarged area that enables interconnections to be formed with greater stability and reliability than by conventional methods.

Abstract: An object of the present invention is to achieve reliable transfer of DTMF signals by preventing the DTMF signals from being doubly received by a receiver due to the DTMF signals being transferred as sound signals to the receiver through a channel for call when transferring the DTMF signals through a channel for control. A communication apparatus in accordance with the present invention is configured to send out a silence to the channel for call when a DTMF signal is transferred so as to prevent the DTMF signal from being sent out as a sound signal onto the channel for call. Furthermore, the communication apparatus is also configured to delete a DTMF signal stored in an FIFO to thereby prevent the DTMF signal from being sent out onto the channel for call.
