A few days ago, GRINM took an important step in the development of the large silicon wafer industry. After one year of preparation, the company first introduced horizontal superconducting magnetic fields and supporting large-scale Czochralski single crystal furnace systems to overcome various difficulties during the epidemic and completed the equipment installation and commissioning, and successfully produced a complete 12-inch single crystal rod with a total weight of more than 320 kg on May 29. The research and development of large-scale single crystals, from thermal field design to process simulation, to crystal pulling debugging, are all completed by the company`s team. The breakthrough and progress of the experiment marked that the company took a key step in the layout of the 12-inch large silicon wafer industry and laid a solid foundation for the smooth implementation of the company's 12-inch integrated circuit silicon wafer industrialization project.
