On July 26, 2023, the 17th China Semiconductor Industry Association Semiconductor Discrete Device Annual Conference and the 2023 China Semiconductor Device Technology Innovation and Industry Development Forum were successfully held in Hangzhou. At the meeting, the China Semiconductor Industry Association officially released the "Top 10 Power Device Enterprises in China's Semiconductor Industry in 2022" list, and Jiangsu Changjing Technology Co., Ltd. was once again selected for four consecutive years. The past decade is considered a golden decade for the development of China's semiconductor industry. In line with the favorable timing, location, and people, local manufacturers are gradually breaking through in their respective advantageous areas and gaining market recognition. Among them, Changjing Technology, as a leading domestic power semiconductor enterprise, has attracted industry attention for its strong technological innovation ability, rich product types, parallel supply chain of Fabless and IDM models, perfect marketing service network, high-quality customer resources, and ability to accurately grasp market opportunities such as new energy vehicles and consumer electronics.

In December 2022, Jiangsu Academy of Science and Technology Development Strategy and Nanjing Institute of Science and Technology Information jointly released the "Top 100 High tech Enterprises in Nanjing for 2022", and Changjing Technology once again made it onto the list. Changjing Technology focuses on the core technology of power semiconductors and adheres to independent innovation. In 2023, the company's key research and development plan in Jiangsu Province, "Key Technology Research on Low Power and High Reliability Superjunction MOS Devices," successfully passed the acceptance inspection of the Provincial Department of Science and Technology; The research and industrialization of new energy vehicle grade chips by Xinshun Microelectronics has been successfully approved by the Science and Technology Achievement Transformation Project of the Provincial Department of Science and Technology. The transformation of research and development achievements related to Changjing Company has been recognized by the competent department. As a leading enterprise in the domestic power semiconductor field, Changjing Technology has always taken it as its responsibility to achieve independent and controllable key core technologies of power semiconductors in China, comprehensively build an independent and controllable semiconductor industry chain, and accelerate the localization and substitution of semiconductor devices in mid to high end application fields. The Department of Science and Technology of Jiangsu Province has released a document titled "Announcement of Proposed Projects for the 2023 Jiangsu Province Science and Technology Achievement Transformation Special Fund". Jiangsu Xinshun Microelectronics Co., Ltd.'s project on the research and industrialization of new energy vehicle grade chips has been successfully selected. Jiangsu Xinshun Microelectronics Co., Ltd. is a subsidiary of Changjing Technology, specializing in the research and manufacturing of semiconductor discrete device wafers. It has 5-inch and 6-inch wafer manufacturing lines and specializes in diode wafers, transistor wafers, and MOSFET wafers. Its products are widely used in the fields of consumer electronics, industrial electronics, and automotive electronics. In 2020, the unveiling ceremony and the first project exchange meeting of the Changjing Technology Electronics High Power Semiconductor Joint Laboratory were grandly held at the University of Electronic Science and Technology of China. Representatives from both sides had further in-depth exchanges and communication on projects such as silicon-based power devices, wide bandgap power devices, and power management chips. Vice President Xu Hongbing congratulated the establishment of the Joint Laboratory on behalf of the University of Electronic Science and Technology of China. He said that while facing the forefront of world technology and major national needs, the school actively faces the main battlefield of the national economy, improves its ability to serve industry development and local economic construction, which is an important task of the "Double First Class" construction. The University of Electronic Science and Technology of China has a profound foundation and a high international academic status in the field of power semiconductors. The school will strongly support the development of the joint laboratory, support the team led by Professor Zhang Bo to conduct in-depth cooperation with Changjing Technology, and promote the integrated development of semiconductor industry, academia, and research.
