1. A semiconductor device comprising:

  • (a) a wiring board having a multilayered wiring structure;

    (b) a first semiconductor chip mounted over the wiring board, including a power controller for controlling power amplification of a signal; and

    (c) a second semiconductor chip mounted over the wiring board, including an antenna switch,wherein electrical coupling between the power controller of the first semiconductor chip and the antenna switch of the semiconductor chip is conducted by (d1) a plurality of first pads formed in the first semiconductor chip, a plurality of first wires respectively electrically coupled to the first pads, and a plurality of bonding wires which have one ends respectively electrically coupled to the first wires and which are formed in the wiring board, and (d2) a plurality of second wires respectively electrically coupled to the other ends of the bonding wires and a plurality of second pads respectively electrically coupled to the second wires and formed in the second semiconductor chip, andwherein the bonding wires include a plurality of first bonding wires formed in the surface of the wiring board and a plurality of second bonding wires formed inside the wiring board.
