密度実装が進む中では、限界がある。In the conventional hybrid integrated circuit, it is necessary to form connection lands on a circuit board on which the semiconductor device is mounted in accordance with the electrodes and pitches of the semiconductor device to be mounted. When the size is restricted, the wiring on the circuit board is wired between the formed lands, so that there is a problem that the wiring cannot be accommodated on the circuit board. As a countermeasure to increase the wiring density, there is a multi-layer circuit board. However, the area of the connection electrodes in each layer is required, and there is a limit in the progress of high-density mounting.
