BYD Semiconductor Expands SiC Mass Production

In 2024, BYD's semiconductor subsidiary, BYD Semiconductor, announced plans to expand its 1200V SiC MOSFET mass production line, thereby increasing the in-house utilization rate for EV inverters. This move signifies more than just vertical integration; it demonstrates the world's largest EV manufacturer's strategic intent to gain control over the upstream of power semiconductor components.

Foundations for Power Semiconductor Supplier Evaluation

A design team preparing for high-volume production of EV inverters faced an initial hurdle in selecting SiC MOSFET suppliers: "We don't know which datasheets to compare." Simply juxtaposing spec sheets proved insufficient as measurement conditions altered the meaning of figures, and reliability data was presented in inconsistent formats across different companies.

SiC Wafer Price Trends and 2026 Outlook

The SiC power semiconductor market in 2024 saw slower-than-expected demand growth, prompting some manufacturers to revise production plans. This "plateau" situation directly impacts a wide range of decisions, from cost calculations for device design to the reassessment of procurement strategies, raising questions about wafer price movements. To discuss the outlook for 2026, we must first consider

Navigating SiC Wafer Procurement Risks

As the adoption of SiC (Silicon Carbide) power semiconductors accelerates, securing a stable supply of wafers is increasingly becoming the biggest bottleneck after design completion, as even the most advanced devices selected during the design phase cannot be mass-produced without available wafers; therefore, to manage supply chain risks, it is crucial to structurally understand "how and where bottlenecks occur in each process.
