? ?On November 26, 2019, Luxiao Technology Co., Ltd., Sinosteel research energy saving Technology Co., Ltd. and Guohong Zhongyu Technology Development Co., Ltd. signed the strategic cooperation agreement on silicon carbide project between Sinosteel research energy saving Technology Co., Ltd. and Guohong Zhongyu Technology Development Co., Ltd. and Luxiao Technology Co., Ltd. in Beijing. It is agreed by the three parties that Sinosteel research and Development Co., Ltd. will take the lead in the research and development of process technology and equipment, Guohong Zhongyu will take the lead in the construction, operation and marketing of industrial projects, Luxiao science and technology will take the lead in equipment manufacturing, project investment and financing, etc., and participate in various works throughout the process. Through close cooperation of all parties, the silicon carbide project will be built into a world-class third generation semiconductor material leader.

? ?In order to adapt to the rapid growth of 5g communication market for high-performance and high-frequency HEMT devices, according to the short-term development plan of Guohong Zhongyu silicon carbide industrialization project, Luxiao technology and / or its holding company will customize about 200 silicon carbide long crystal furnaces for the silicon carbide industrialization project led by Guohong Zhongyu. In this cooperation, the three parties mainly rely on the research and development achievements of Sinosteel research and Guohong Zhongyu in the growth technology of silicon carbide crystal materials, combined with the design technology of vacuum crystal growth equipment of Luxiao technology and rich equipment manufacturing technology and experience, and jointly develop the 4-inch, 6-inch and 8-inch applicable to the technological requirements of Sinosteel research At present, the first two sets of sublimation process silicon carbide long crystal furnace have completed the equipment performance acceptance and delivery for use, and the optimized silicon carbide long crystal furnace equipment will be applied in the silicon carbide industrialization project led by Guohong Zhongyu.

? ? At the same time, the research and development achievements of Sinosteel research and Guohong Zhongyu in silicon carbide substrate processing, cleaning and testing, combined with the advantages of Luxiao technology in sapphire substrate processing technology, product quality management and production organization experience, the three parties jointly build silicon carbide substrate processing center, which can meet the rapid growth of 6-inch and above size level silicon carbide at home and abroad The demand of substrate market, the improvement of substrate quality and yield level will play an important role.

It is of far-reaching strategic significance for the three parties to achieve a strong alliance to promote the business layout and development of silicon carbide field, enhance the R & D and innovation ability of enterprises, and improve the market competitiveness.
