Yinhe Semiconductor's RMB 1.6 billion large-size silicon wafer phase II project enters mass trial production

Recently, there has been new developments in the Ningxia Yinhe Semiconductor Integrated Circuit Large-Size Silicon Wafer Phase II Project.

According to Xinhua News Agency, the second phase of Yinhe Semiconductor's integrated circuit large-size silicon wafer project is currently undergoing mass trial production and will gradually reach full production based on market conditions.

In addition, Hao Yuzhou, head of Yinhe Semiconductor, said that with the commissioning and full production of the company's Phase II project, Yinhe Semiconductor will become one of the domestic leaders in large-size silicon wafer production.

It is understood that the Ningxia Yinhe Semiconductor Integrated Circuit Large-Size Silicon Wafer Phase II Project was started and laid the foundation on March 18, 2018, with a total investment of 1.6 billion yuan by Ningxia Yinhe Semiconductor Technology Co., Ltd. After the project is completed, it can produce 4.2 million 8-inch semiconductor-grade monocrystalline silicon wafers and 2.4 million 12-inch semiconductor-grade monocrystalline silicon wafers annually. The products involve electronics, semiconductors, integrated circuits, communications, automobiles, medical care, national defense and other industrial fields.

According to the Economic Daily at the time, the Yinhe Semiconductor Integrated Circuit Large Silicon Wafer Phase II Project, by forming a technical team of experts from home and abroad, developed the 40-28nm process 300mm semiconductor polished silicon wafer manufacturing technology (2020) with independent intellectual property rights based on the introduction and absorption of 65-45nm process 300mm semiconductor polished silicon wafer manufacturing technology (2019), and established a complete technology development, production operation, quality management, and marketing operation system.

It is worth mentioning that according to an earlier report by People's Daily, the Ningxia Yinhe large silicon wafer project has completed an investment of 1.11 billion yuan, and 12-inch large silicon wafers and 32-inch quartz crucibles are undergoing mass trial production and will gradually reach full production within the year.
