Product objectives

From EVs to AI data centers: Expanding demand fuels SiC market growth

The SiC device market is set for strong expansion through 2031, driven by accelerating electrification and energy efficiency demands across industries. It is expected to reach around $11B by 2031, supported by a robust ~20% CAGR and broad adoption across automotive, industrial, and energy applications.

BEVs remain the dominant growth engine for SiC, with adoption accelerating as higher-voltage architectures become standard. SiC enables greater efficiency, range, and power density, making it the preferred solution for next-generation inverters and fast-growing 800V platforms. Rail applications continue to adopt SiC in a project-driven manner.

SiC is becoming a key enabler of high-power EV charging, where efficiency and compact design are critical. Its strong position in fast chargers supports the rapid expansion of charging networks and aligns with the shift toward higher power levels.

The growth of renewable energy and storage is driving increasing use of SiC in PV solar inverters and BESS. Its efficiency and reliability support grid integration of intermittent energy sources, making it essential for scalable clean energy infrastructure. While wind adoption remains more gradual due to cost and reliability trade-offs.

Data centers and AI infrastructure boost demand for high-power SiC in power supplies, accelerating adoption in >3kW systems and next-gen architectures.

Vertical integration and 200mm transition reshape SiC supply dynamics

Vertical integration remains the dominant strategy in Power SiC, with leading IDMs such as STMicroelectronics, Wolfspeed, ROHM, and onsemi strengthening internal wafer capabilities or securing long-term supply. At the same time, key OEMs, like Infineon and Bosch, continue with external wafer and epiwafer supply from key players, such as SiCC, TankeBlue, …etc.

The evolution in SiC ecosystem continues, with players extend to another level, especially in the SiC materials. Coherent, Tankeblue, GlobalWafers, and SK Siltron CSS move into the epi segment, to enlarge the market access. The SiC foundry segment remains relatively small, but it’s attracting new entrants and ongoing investments due to the total market growth.

The shift to 200mm wafers marks a major inflection point, with companies like Wolfspeed, Infineon, and Bosch leading high-volume production as of 2026. This transition is driving large-scale capacity expansions and will be critical for improving cost efficiency and meeting future demand.

More than $30B in global investments highlights strong commitment to SiC, with Asia leading the expansion, particularly China and the broader Asian region, while North America and Europe continue the investment through key companies like Wolfspeed, Bosch and STMicroelectronics.

China is rapidly strengthening its position, combining market of end applications, and growing market shares of market players, such as SICC and TankeBlue at wafer level and UNT at device level. To deal with uncertainty of geopolitics, international players have also developed strategies to enter Chinese market and to secure the supply with cost-competitiveness.

Power SiC - From 6” to 8”, new design and higher voltage

The transition to 8” wafers is accelerating in view of the advantages of production scaling and potential cost-competitiveness. Players, including Wolfspeed, Infineon, and Bosch, are ramping up device manufacturing on 200mm platform, and more players to follow. In the near term, 6” substrates are expected to remain the major platform, but current expansion of capacity is mainly based on 200mm.

At the same time, wafer technology continues to advance through the adoption of thinner substrates and improved processing techniques, such as laser slicing. These innovations are primarily driven by the needs to enhance yield and reduce costs. Early-stage developments toward 300mm wafer are also emerging, with Chinese players, such as SiCC , demonstrated various types of  12” wafers.

On the device side, trench SiC MOSFETs have been commercialized by Infineon, Bosch, and ROHM, more players plan to launch next-generation platforms with trench design. At the same time, SiC planar MOSFETs continue showing improvement of performance. SiC JFETs also gain attention due to the potential in some emerging applications.

More advanced design in SiC device is going from concept to product, especially in view of the demand in  high-voltage device. The first commercialized super-junction SiC MOSFET is about being launched in the next year by Infineon, along with various players exploring the technology, such as STMicroelectronics, GE Aerospace and more. As 2026, some players launched products or prototypes towards 10kV class, such as Wolfspeed, InventChip, Navitas, and Coherent.
