According to industry news, the second phase of a large fund invested in Huahong Chengdu, a new company of the "unfinished" wafer factory Chengdu GlobalFoundries, with a subscribed investment of 3.6 billion yuan!

According to reports, Huahong Chengdu has recently completed its first capital increase since its establishment. The registered capital has increased from 100 million yuan to 22.8 billion yuan. Among them, the original sole shareholder and a member of the Huahong Group, Shanghai Huali Microelectronics Co., Ltd. The company (hereinafter referred to as "Huali Micro") subscribed to Huahong Chengdu's new registered capital of 11.6 billion yuan; Chengdu High-tech Lianxin Technology Industry Investment Co., Ltd. subscribed to 7.5 billion yuan; National Integrated Circuit Industry Investment Fund Phase II Co., Ltd. Then subscribed 3.6 billion yuan.

After the capital increase is completed, the three parties hold approximately 51.32%, 32.89% and 15.79% of Huahong Chengdu's registered capital respectively. At present, Huahong Chengdu's registered capital of 22.8 billion yuan has exceeded domestic wafer fabs such as Shanghai Huahong Grace Semiconductor Manufacturing Co., Ltd. and Semiconductor Manufacturing International Corporation (Shanghai) Co., Ltd.
It is understood that on the east side of the Chengdu High-tech Comprehensive Free Trade Zone, the GF project, which originally planned to invest nearly US$10 billion, has now been replaced by the logo of "Huahong Integrated Circuit (Chengdu) Co., Ltd." at the gate.​

Zhongke Zhongyi Semiconductor Technology Co., Ltd., recently, Suzhou Zhongke Zhongyi Semiconductor Materials Co., Ltd. (hereinafter referred to as "Zhongke Zhongyi") independently developed large-size silicon-based gallium nitride for use in the field of power electronics. (GaN-on-Si) epitaxial wafer production line was officially built and put into use. This means that the production of power gallium nitride epitaxial wafers in the direction of power electronics will get rid of dependence on imports and become completely independent and controllable.

Relying on its advanced R&D and industrialization base, Zhongke Zhongyi focuses on the R&D and manufacturing of large-size silicon-based gallium nitride epitaxial wafers for third-generation semiconductors, and is committed to providing high-quality gallium nitride material solutions for the power electronics field. According to reports, the gallium nitride epitaxial wafer produced by Zhongke Zhongyi has a gallium nitride layer thickness of about 5 μm, no cracks on the surface, and a warpage of less than 100 μm. At room temperature, the HEMT structure has a sheet resistance of 465Ω/sq, a two-dimensional electron gas (2DEG) concentration of about 8×1013cm-2, a 2DEG mobility of greater than 2000 cm2/Vs, and intra-chip and inter-chip unevenness of less than 1%, which can meet The development and application needs of power devices in the field of power electronics have significantly reduced the production cost of gallium nitride epitaxial wafers while getting rid of dependence on imported equipment.

According to the official website, Yicu Gas was founded in 2006 and focuses on electronic special gases, electronic chemicals, electronic bulk gases, industry supporting special equipment, engineering, and operation and maintenance services. Through independent research and development and independent innovation, we will gradually implement a full range of domestic substitutions. The company has multiple business divisions. Through R&D centers, industrial bases, various sites and other models, the company has increased product categories and R&D investment, and comprehensively deployed in semiconductor, photovoltaic, panel, aerospace, pharmaceutical, precision chemistry and other industries.

Judging from the current equity structure, the controlling shareholder of Yicu Gas is Shanghai Yicu New Materials Group Co., Ltd., and the actual controllers are Li Jianxin and Zhu Yan. Among them, Shanghai Yicuo New Materials Group Co., Ltd. is a company in which Li Jianxin and Zhu Yan hold 100% of the shares. They directly hold 47.344% of the company's shares and are the company's controlling shareholders; Li Jianxin and Zhu Yan each directly hold 25.725% of the company's shares. % and 4.801% of the shares; Li Jianxin controls 1.589% of the company through Tianjin Henry Enterprise Management Partnership (Limited Partnership), Tianjin Henghui Enterprise Management Partnership (Limited Partnership), and Tianjin Henry Huirui Enterprise Management Partnership (Limited Partnership) respectively. , 1.047% and 0.795% of the shares. Therefore, Li Jianxin and Zhu Yan collectively control 81.301% of the company's shares and are the actual controllers of the company.​

According to the official WeChat account of Shuozhou Municipal People’s Government, on December 9, the first silicon wafer of Sany Shuozhou Phase II ultra-thin monocrystalline silicon wafer project successfully rolled off the production line. A square rod of about 830mm long monocrystalline silicon can be turned into 4,580 silicon wafers after more than 100 minutes of processing. The relevant person in charge said that all the main equipment for the project will arrive in early January next year, and the entire project will be put into production at the end of January. Based on industry needs, "Sany" Group will continue to increase investment and develop the photovoltaic manufacturing industry chain of "monocrystalline silicon - slices - solar cells - photovoltaic modules".
