What Are Wafers?

Wafer refers to a silicon wafer used in silicon semiconductor integrated circuit manufacturing. Since it has a round shape, it is called a wafer; on the silicon wafer, it can be processed into various circuit element structures and become an IC with a specific electrical function. product. The original material of the wafer is silicon, and the surface of the crust is inexhaustible silicon dioxide. Silica ore is extracted through an electric arc furnace, chlorinated with hydrochloric acid, and distilled to produce high-purity polycrystalline silicon with a purity of 99.999999999%.

Wafers are the basic materials for manufacturing semiconductor chips. The main raw material for semiconductor integrated circuits is silicon, so the corresponding silicon wafers.

Silicon is widely present in nature in the form of silicates or silica in rocks and gravel. The fabrication of silicon wafers can be summarized in three basic steps: silicon extraction and purification, single crystal silicon growth, and wafer formation.
