Special Note: There will be slight scratches during wafer transportation.

​Multiple colors are shipped randomly.
  The original material of the wafer is silicon, and the surface of the earth’s crust is inexhaustible of silicon dioxide. Silica ore is refined by electric arc furnace, hydrochloric acid is chlorinated, and after distillation, high-purity polysilicon is made, and its purity is as high as 99.999999999%. The wafer manufacturer then melts the polysilicon, implants the seed crystal in the melt, and then slowly pulls it out to form a cylindrical single crystal silicon rod. Since the silicon rod is oriented by a crystal plane The identified seed crystals are gradually formed in the molten silicon raw material, and this process is called “growth”. After the silicon ingot is cut, rolled, sliced, chamfered, polished, laser engraved, and packaged, it becomes the basic raw material of the integrated circuit factory-silicon wafer, which is the “wafer”.
               The finished silicon wafer manufactured by the chip, after cutting, the package is an IC!
Due to the sophisticated manufacturing process, the factory’s security measures are perfect. Few complete silicon wafers can be seen on the market, and I am fortunate to bring a small amount of them for sale at a cheap price.
It is suitable for decoration or display at the counter of Digital City.
It is also suitable for science and technology schools to make textbooks for students.
