Silicon Manufacturing Process:


   Silicon is used in electronic circuits from TV remote to Rockets. They are used in Integrated circuits, Computer processors, RAM, mobile ICs etc.

    The manufacturing process is shown below:

 Step 1:  Filtering Silicon in Sand:

    Silica is found in earth's Crust (top layer of earth structure). It is taken by filtering sand.

Manufacturing of Ingot:


Pure Silicon is then heated until it reaches molten state. The boiling point of Silicon is 3265 °C.

Then the silicon is made into Wafer.

Then the Wafer is separated into an individual die.

Then the die is finally sent to companies like Intel, Qualcom etc to manufacture IC's.
