A semiconductor device includes a semiconductor substrate having an active region, a plurality of gate electrodes formed on the active region with a gate insulating film therebetween, and a dummy pattern formed on the active region in at least a part thereof between the gate electrodes. Each transport container has a support portion formed on an upper portion thereof. Further, a first filter and a second filter are separately fabricated, each having at least one film bulk acoustic resonator which is fabricated by depositing a lower electrode, a piezoelectric layer, and an upper electrode in this respective order. The audio path selector interconnects the central processing unit and the USB switch, and has a first audio path for output of audio signals from the central processing unit to the audio signal transmission path, and a second audio path for output of audio signals from the audio signal transmission path to the central processing unit.
