Have you googled "PolyCrystalline Silicon Fabrication?" There is a lot of stuff out there.

Edit: Plus we have no idea what sort of level this should be at. These sort of general questions tend to not garner very much help from PF.

Cheers,

Hi there,

The poly crystalline silicon fabrication process is a method used to produce polycrystalline silicon, which is a type of silicon with multiple small crystals. This process involves several steps, including purification of the silicon, melting it into a liquid, and then solidifying it into polycrystalline form.

To start, the raw silicon is purified through a series of chemical and physical processes to remove any impurities. Once the silicon is pure, it is then melted in a furnace at high temperatures. The molten silicon is then poured into a mold, where it is allowed to cool and solidify into a block of polycrystalline silicon.

After solidification, the block of polycrystalline silicon is cut into thin wafers using a saw. These wafers are then polished to create a smooth surface. Next, the wafers undergo a series of treatments to create an electrical junction, which is necessary for the silicon to function as a semiconductor.

The final step in the fabrication process is to add metal contacts and a protective coating to the wafers. This allows the polycrystalline silicon to be used in various electronic devices, such as solar cells, microchips, and sensors.

For more information on the poly crystalline silicon fabrication process, you can visit websites such as the National Renewable Energy Laboratory (NREL) or the Semiconductor Industry Association (SIA). These sites provide detailed information on the process and its applications.

I hope this helps with your assignment. Good luck!
