A wafer made this way is the main material for semiconductors. The larger the diameter of a wafer is, the greater the number of chips that can be produced. PS: Silicon is extracted from Silica sand, also known as quartz sand, white sand, or industrial sand. It is made up of: silica and oxygen (SiO2).
It has to go through a process to make the wafers semiconductive. First, wafers go through the oxidation process. Oxygen or water vapor is sprayed on the wafer surface to form a uniform oxide film. This oxide film protects the wafer surface during the subsequent processes and also blocks current leakage between circuits.
