Short-term slowdown, long-term SiC

Despite a temporary slowdown in BEV (1) shipments, the SiC (2) market remains on a long-term growth trajectory. At Yole Group, analysts expect the power SiC market to exceed $10 billion by 2029, driven by a strong rebound anticipated in 2026. Indeed, the CAGR between 2024 and 2023 should be close to 20%.

Meanwhile, other OEMs, especially from China, are gaining ground. BYD, Nio, Geely, and Xiaomi are expanding their SiC-based BEV portfolios.
Despite these positive trends, the overall market deceleration has impacted the revenue growth of key SiC suppliers such as STMicroelectronics and onsemi, though Infineon Technologies continues to grow, supported by its diversified applications across both automotive and industrial sectors.

While many players are expanding capacity, especially in transitioning from 6-inch to 8-inch wafers, current end-system demand may not yet justify this scale.

Key factors to monitor include wafer quality, yield, and supply chain efficiency. As competition intensifies, vertical integration becomes more critical. Leading companies, including STMicroelectronics, onsemi, Wolfspeed, and Infineon Technologies, are doubling down on internal wafer manufacturing and module production to meet their billion-dollar revenue targets.

At Yole Group, analysts track these trends closely through the Power SiC/GaN Compound Semiconductor Market Monitor, part of their Market Monitor Collection. Yole Group provides in-depth insights into supplier strategies, capacity planning, and investment directions, offering stakeholders a clear understanding of how the SiC landscape is evolving.

As an example, Yole Group offers a deep and strategic analysis of STMicroelectronics’ innovative expansion in China’s dynamic semiconductor landscape. With decades of industry expertise and data from a wide range of in-house market monitors and reports, Yole Group identifies STMicroelectronics’ approach as one of the most ambitious moves among non-Chinese semiconductor players.
Faced with rising competition and China’s push for local sourcing, the leading semiconductor company has adopted a unique “become Chinese in China” strategy. Yole Group’s analysts spotlight three key partnerships underpinning this approach: a $3.2 billion joint venture with Sanan Optoelectronics for SiC devices, a manufacturing collaboration with Hua Hong Semiconductor for 40nm automotive MCUs, and a strategic investment in GaN leader Innoscience. These moves are designed to localize production, support Chinese OEMs, and secure long-term market share in China’s EV and industrial sectors.

Yole Group’s comprehensive market intelligence provides critical insights into the risks and rewards of STMicroelectronics’ localization efforts. This detailed analysis, based on the Power SiC/GaN Compound Semiconductor Market Monitor, Q1 2025, suggests that these bold moves could significantly boost STMicroelectronics’ growth from 2026 while also shaping the competitive landscape in SiC markets.
