Wafer refers to the silicon wafer used in the production of silicon semiconductor integrated circuits, because of its circular shape, it is called wafer; It can be processed into various circuit component structures on silicon wafers, and become IC products with specific electrical functions. The original material of the wafer is silicon, and the earth's crust is inexhaustible silica. The silica ore is refined by electric arc furnace, chlorinated by hydrochloric acid, and distilled to make high purity polysilicon, its purity is as high as 99.999999999%.
A chip is also known as a microcircuit, microchip, or integrated circuit (IC). A small piece of silicon containing an integrated circuit, often part of a computer or other electronic device.
chip (chip) is a general term for semiconductor components. It is the carrier of integrated circuit (IC, integrated circuit), which is segmented by wafer.
