The silicon wafer manufacturing process is crystal pulling, silicon wafer dicing, silicon wafer grinding, chamfering, etching, polishing, cleaning and inspection, among which crystal pulling, silicon wafer polishing and inspection are the core links of silicon wafer manufacturing. As the basic semiconductor substrate, silicon wafers must have high standards of purity, surface flatness, cleanliness, and impurity contamination to maintain the original designed functions of the chip. The high-specification requirements of semiconductor silicon wafers make its manufacturing process complicated. The four core steps include polysilicon purification and polysilicon ingot casting, single crystal silicon wafer growth, and silicon wafer cutting and shaping. As a raw material for wafer fab, the quality of silicon wafers directly determines the stability of the silicon wafer application process. Large-size silicon wafers have become the future development trend of silicon wafers. In order to improve production efficiency and reduce costs, more and more large-size silicon wafers are used.
