<p>PURPOSE:To eliminate the conductive line for an electric coupling and to enable to individual superpose layers by employing light or electromagnetic waves of various wavelengths generated from a semiconductor laser or a photodiode when multilayers forming three-dimensional elements are coupled to each other. CONSTITUTION:Layers 1, 1' formed with respective devices are coupled through an insulating film 2, and a signal which is fed to a sensor or an input unit formed at the layer 1 is fed to a light emitting device 5 such as a semiconductor laser which is contacted with the film 2 side of the layer 1. Then, a laser signal which is produced at the device 5 is fed to a photodetector 6 which is formed at the layer 1' and is contacted with the film 2, and an obtained electric signal is fed externally. In this structure, a light or electromagnetic wave which is produced from a semiconductor laser or a photodiode is emitted for coupling, thereby eliminating the special device for coupling. In this manner, the respective device layers 1, 1' are separately formed, and may be superposed later.</p> |
