○Small-Scale Semiconductor Factory

     Most household appliances and electronic devices around us use semiconductors. Semiconductors are small components necessary for transmitting radio waves for communication, increasing the volume of speakers, controlling motors, and setting calculations and timers.

    Semiconductors are often produced in factories costing tens of billions or trillions of yen. However, in a society that strives for self-sufficiency in all things, municipalities also produce and consume the necessary amount, following a local production for local consumption model. Therefore, these factories are small-scale facilities that have been miniaturized, similar to 3D printers.

    In addition to semiconductors, printed circuit boards containing components such as resistors, capacitors, transformers, diodes, and transistors must be manufactured using 3D printers.

    This process involves obtaining metal materials from minerals and incorporating semiconductors and printed circuit boards produced in small-scale factories into products. Instead of large-scale factories, these are done in small-scale factories using local resources as much as possible. This approach realizes manufacturing with the minimum necessary production quantity and minimal environmental impact. It also ensures that major components can be used without being monopolized by anyone. These factories are also established in municipal manufacturing facilities.
