Youyan Semiconductor Materials Co., Ltd. successfully produced a 12-inch single-crystal silicon ingot from its large-scale superconducting magnetic field system.

Recently, Youyan Semiconductor Materials Co., Ltd. has taken an important step forward in the development of the large silicon wafer industry. After a year of careful planning and preparation, the company has, for the first time, introduced a horizontal superconducting magnetic field system along with a corresponding large-scale Czochralski single-crystal growth furnace. Despite numerous challenges posed by the pandemic, the company successfully completed the installation and commissioning of the equipment and has now... 5 Moon 29 Successfully drew a complete one today. 12 Inch single-crystal ingot, with a total ingot weight exceeding 320 kilograms. The R&D effort for this large-size single crystal—from thermal field design and process simulation to crystal growth adjustment—was entirely carried out by the Youyan Semiconductor team. The breakthroughs and progress achieved in these experiments mark the company’s... 12 The company has taken a crucial step in the industrial layout for large-inch silicon wafers. 12 The successful implementation of the industrialization project for large silicon wafers used in inch-scale integrated circuits has laid a solid foundation.
