Most of the Electronic devices are today built on silicon substrates.

polysicilicon manufacturing Mersen

 

The silicon element is very common on earth. A dedicated industry is transforming natural silicon oxides into a multi-crystalline and purified form of silicon called the “Polysilicon”.

Firstly, the purification process requires the usage of corrosive fluids such as the hydrochloric acid.
