Attention:
There will definitely be slight scratches on wafer 's surface during transportation. They are not easily visible to eyes. Please make sure that you don't mind before purchasing.

Silicon Wafer Introduction:
The original material of the wafer is silicon, and the surface of the earth's crust is inexhaustible. The silica ore is refined by an electric arc furnace, chlorinated with hydrochloric acid, and distilled to produce high-purity polycrystalline silicon with a purity of up to 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 ingot, because the silicon ingot is oriented by a crystal plane. The determined seed crystals are gradually formed in the molten silicon raw material, and this process is called "long crystal". After the silicon ingot is cut, barreled, sliced, chamfered, polished, laser engraved, and packaged, it becomes the basic material of the integrated circuit factory - silicon wafer, which is the "wafer".
 
The finished silicon wafer manufactured by the chip, the package after cutting is the IC!

It is suitable as decorations, or placed at the counter of digital city. It is quite high-grade for gifts to relatives and friends! It is also suitable for science and technology schools as teaching materials for students.

Package Included:
- 1 x Silicon Wafer
