Zhejiang Jinruihong Technology Co., Ltd. was established in June 2000 and is located in Ningbo Free Trade Zone. It is one of the earliest companies in China specializing in the manufacturing of integrated circuit silicon wafers. It is also a leading technology, advanced supporting facilities, perfect scale and excellent efficiency in mainland China. The semiconductor silicon wafer manufacturing enterprise is one of the few semiconductor silicon material enterprises in my country with a complete industrial chain of silicon single crystal ingots, silicon grinding sheets, silicon polishing sheets, and silicon epitaxial sheet manufacturing. After more than 20 years of continuous research and development and production practice, we have formed a deep technical accumulation, mastered a series of unique proprietary technologies and know-how such as nitrogen-doped direct-pull silicon single crystal, trace germanium doped and heavy doped, and built a large A characteristic industrial system that combines size and small size, scientific matching of mature products and new products, comprehensive utilization of equipment and raw materials, balanced light doping and heavy doping, and integration of upstream and downstream of the industrial chain. Some unique competitive advantages have been formed, including outstanding technological and R&D advantages, obvious first-mover advantages in the industry, and significant talent and scale advantages.

The company has innovative platforms such as provincial enterprise research institutes, provincial R&D centers, municipal academician workstations, etc., and has won the second prize of the National Technology Invention Award, the first prize of Zhejiang Province Technology Invention Award, the first prize of Zhejiang Province Science and Technology, and the progress of Zhejiang Province Science and Technology The third prize, the Ministry of Industry and Information Technology's major technological invention award, the China Semiconductor Innovation Products and Technology Award, the Ningbo Municipal People's Government Quality Innovation Award, etc., have been successively recognized as the National 863 Achievement Industrialization Base, the National High-Tech Industrialization Demonstration Engineering Unit, and the National Integrated circuit enterprises, national innovative pilot enterprises, Zhejiang Province’s innovative demonstration enterprises, Zhejiang Province’s “hidden champion”, Ningbo City’s single championship demonstration enterprises, etc.

Jin Ruihong is an important research and development and industrial platform for the semiconductor silicon wafer business of Hangzhou Lion Microelectronics Co., Ltd. (Securities abbreviation: Lion Micro, stock code: 605358). In the future, we will use multi-channel efforts to expand the field of semiconductor technology in a timely manner, improve core competitiveness, and strive to build the company into an internationally competitive and professional outstanding supplier of semiconductor materials!
