As the market demand for new energy vehicles grows, more automakers are seeking the transition from 400V to 800V high-voltage platforms, catering to consumers' daily commuting and long-distance travel needs.

SiC chips are widely used in key components such as electric drive inverters, on-board chargers (OBCs), and DC-DC converters due to their excellent high-voltage and high-temperature resistance characteristics. As the demand for SiC chips continues to rise, XinDong-Semi is establishing long-term partnerships with high-quality suppliers to ensure a stable supply of SiC chips and further develop the SiC power module field.

XinDong-Semi, established as a subsidiary of Great Wall Motor in November 2022, focuses on independent R&D to achieve self-sufficiency in power semiconductor supply. The company aims to develop third-generation SiC power semiconductor modules and application solutions.

In February 2023, the construction of XinDong-Semi's manufacturing base for the "Third-Generation Semiconductor Module Assembly and Testing Project" in Wuxi city, Jiangsu Province commenced, and the project saw its first production line starts operation in October. With a total investment of 800 million yuan, the facility covers an area of approximately 30,000 square meters and has an estimated annual production capacity of 1.2 million sets of automotive-grade modules.
