According to publicly announced information, the project that passed the acceptance inspection is an important upgrade and expansion of Ningbo BYD Semiconductor on the existing production line, with a total investment of about 744 million yuan. It relies on the existing factory buildings in Ningbo Free Trade Zone to complete the construction and renovation, and completed the construction and commissioning in November 2024. In November 2025, it successfully passed the environmental protection acceptance inspection for completion. After the upgrade, the production scale will be optimized and adjusted. In addition to retaining some IGBT and FRD chip production capacity, the focus will be on adding new power semiconductor chip production capacity such as silicon carbide (SiC). The products cover multiple categories such as TVS, SBD, PD, CMOS, etc., which will further improve BYD's product matrix in the power semiconductor field. Tracing the development trajectory of the enterprise, the growth of BYD Semiconductor in Ningbo cannot be separated from the accumulation of its original industrial foundation. Its predecessor was Ningbo Zhongwei Semiconductor, established in 2008, and the core production line was initially built by the latter. After being acquired by BYD Semiconductor, the company continued to increase construction investment and technological upgrading efforts, gradually strengthening chip production capacity through multiple phases of project promotion, forming a division of labor model of "former Zhongwei responsible for 6-inch integrated circuit chip processing production line, BYD leading other projects", effectively integrating the advantages of the original production line with BYD's technical resource reserves, laying a solid foundation for this project upgrade. It is worth noting that the development of this industry carrier cannot be separated from the early exploration of industry predecessors.

Feng Mingxian, former chairman of Ningbo Zhongwei Semiconductor, has been deeply involved in the semiconductor industry for many years. With his profound industry insights, he has promoted the layout of the industry. In 2002, he led the relocation of TSMC Plant 1 to Ningbo and established Zhongwei Semiconductor (Ningbo) Co., Ltd., directly laying a solid foundation for the start of the semiconductor industry in Ningbo. Despite the company's subsequent setbacks and acquisition by BYD, Feng Mingxian's exploration and practice not only accumulated valuable industry experience, but also effectively promoted exchanges and cooperation in the semiconductor industry between the two sides of the Taiwan Strait, becoming an important imprint in the history of Ningbo's semiconductor industry development. As a leading domestic power semiconductor IDM enterprise, BYD Semiconductor has mature wafer manufacturing processes and strong technological accumulation. Its self-developed automotive grade IGBT, SiC chips and other products have been widely used in the field of new energy vehicles, and its core chip self-sufficiency rate ranks among the top in the industry. The successful acceptance of the Ningbo project will further enhance its production capacity and technological competitiveness, and better respond to the rapidly growing application demands in fields such as new energy vehicles and industrial control. Industry insiders analyze that the current power semiconductor industry is upgrading towards high efficiency and high integration, and the market penetration rate of third-generation semiconductor materials such as silicon carbide is rapidly increasing. The commissioning of BYD's Ningbo wafer factory will not only provide more solid semiconductor support for the BYD Group's industrial chain, but also assist in the domestic power semiconductor localization process through external market supply. In the future, with the comprehensive promotion of the project, it is expected to further optimize the layout of the regional semiconductor industry, injecting new momentum into the high-quality development of the semiconductor industry in Ningbo and even the whole country.
