According to reports, new energy vehicles are gradually advancing from 400V to 800V high-voltage platforms to meet the market needs of consumers for daily travel and long-distance travel. SiC chips (silicon carbide) are widely used in key applications such as electric drive inverters, electric vehicle on-board charging (OBC) and DC-DC converters (DC-DC) due to their excellent characteristics such as high voltage resistance and high junction temperature applications. in parts.

Great Wall Motors said that the signing of a strategic cooperation agreement with STMicroelectronics on the SiC chip business will further promote Great Wall Motors’ vertical integration and increase its efforts in new energy development.

Iit noted that STMicroelectronics also signed a long-term silicon carbide (SiC) supply agreement with Li Auto in December last year. According to the agreement, STMicroelectronics will provide silicon carbide MOSFETs to Li Auto to support Li Auto’s strategic plan to enter the high-voltage pure electric vehicle market.

The 800V high-voltage pure electric platform launched by Li Auto uses STMicroelectronics’ third-generation 1200V SiC MOSFET technology in the electric drive inverter.

Silicon carbide (SiC) is a disruptive compound semiconductor material whose inherent properties enable better performance and energy efficiency than silicon-based semiconductors in critical, high-growth power applications in electric vehicles and industrial processes. — all of which are key parameters and elements of successful automotive and industrial systems. Upgrading from 6-inch wafers to 8-inch wafers can almost double the available area for manufacturing integrated circuits, with 1.8-1.9 times the effective yield per wafer prior to the upgrade, resulting in a significant increase in capacity.

SmartSiC is Soitec’s proprietary technology, based on Soitec’s proprietary SmartCut technology, which cuts a thin layer from a high-quality silicon carbide donor wafer and bonds it to the surface of the low-resistance polysilicon wafer to be processed. The result is a substrate with improved chip performance and manufacturing yields. In addition, high-quality silicon carbide donor wafers can be reused multiple times, thus significantly reducing the total energy consumption for donor processing.
