6 inches, 8 inches, 12 inches and so on. After cutting, grinding, polishing and other processes, the single crystal silicon rod becomes a silicon polishing sheet. According to its diameter, it is divided into 6 inches, 8 inches, 12 inches and other specifications. The larger the diameter, the higher the requirements for materials and technology. Single crystal silicon rod is shaped or drawn in the furnace by zone melting or Czochralski method, which is a single crystal silicon rod with silicon atoms rearranged according to the crystal lattice arrangement direction of seed crystal.
