Great Wall Motor-backed XinDong-Semi partners with STMicroelectronics

Beijing (Gasgoo)- On March 8, XinDong-Semi, the chip arm of Great Wall Motor, and STMicroelectronics entered into a strategic cooperation agreement aimed at driving the development in silicon carbide (SiC) power module technology. 

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.
