unetron, a silicon wafer manufacturing company, offers silicon wafer: FZ Silicon wafer, Test Wafer Monitor Wafer Dummy Wafer, Test Wafer, CZ wafer, epitaxial wafer, polished wafer, etching wafer.

The silicon wafer manufacturing process is crystal pulling, dicing, grinding, chamfering, etching, polishing, cleaning and inspection, among which crystal pulling, wafer polishing and inspection are the core links of Si wafer manufacturing. As the basic semiconductor substrate, silicon wafers must he 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 proceomplicated. The four core steps include polysilicon purification and polysilicon ingot casting, single crystal Si wafer growth, and Si wafer cutting and shaping. As a raw material for wafer fab, the quality of silicon wafers directly determines the stability of the wafer application process. Large-size silicon wafers he 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.
