Abstract:
A stacked substrate body for controlling an external device, comprising:a first substrate having a field programmable first functional section for acquiring required functions that can be changed flexibly corresponding to a plurality of second functional sections and the external device by connecting to and disconnecting from each other a plurality of pre-arranged circuit elements through programmable switching means, and a plurality of first input-output terminals corresponding to the first functional section; a plurality of second substrates having the second functional sections respectively which have functions for controlling the external device related to the first functional section, and a second input-output terminal corresponding to the second functional section and being located on the first substrate; connecting lines among the second substrates being formed on the first substrate as the programmable first functional section and being flexibly connected and disconnected electrically corresponding to the second functional sections by controlling the first functional section; and the first and second substrates being stacked together so that the first and second input-output terminals are electrically interconnected.
