What Kind Of Chemicals Are Used In Making Computer Chips?

The most common type of semiconductor material used is silicon. Silicon dioxide, or sand (the main material in computer chips). Other materials used in making computer chips include germanium and gallium arsenide.

Step 1: Start With Sand

The process of making a computer chip starts with a particular kind of sand called silica sand, which is made of silicon dioxide.

Step 2: Purify to Obtain Silicon Ingot

A silicon ingot is a cylindrical piece of extremely pure silicon grown in a controlled environment. Electronic-grade silicon, which has a purity of 99.9999 percent, is produced by a number of purification and filtering procedures.
