What's Happening?
STMicroelectronics is a significant player in the United Kingdom's Silicon Carbide (SiC) semiconductor device market, competing with other major global suppliers such as Infineon Technologies, Wolfspeed, ON Semiconductor, Rohm Semiconductor, and Mitsubishi
Electric. These companies maintain application engineering teams in the UK to support original equipment manufacturer (OEM) design-ins, focusing on device performance, qualification pedigree, and supply assurance. The UK market for SiC devices is projected to grow significantly, driven by automotive electrification and industrial energy efficiency mandates. The market is expected to expand from approximately USD 85-110 million in 2026 to over USD 480-620 million by 2035. The UK remains heavily reliant on imports for finished SiC devices, with over 85-90% sourced from suppliers in the United States, Germany, Japan, and China.
Why It's Important?
The expansion of the SiC market in the UK is crucial for the country's automotive and industrial sectors, which are increasingly adopting SiC technology for its superior performance in high-efficiency applications. The growth in demand for SiC devices is aligned with the UK's goals for automotive electrification and energy efficiency, supporting the transition to electric vehicles and more efficient industrial processes. This market growth presents opportunities for global suppliers to strengthen their presence in the UK, while also highlighting the UK's dependency on international supply chains for critical semiconductor components. The development of domestic capabilities in SiC technology could enhance the UK's technological independence and support its industrial strategy.
What's Next?
As the UK market for SiC devices continues to grow, there will likely be increased investment in domestic research and development, as well as potential government support to establish local manufacturing capabilities. The UK's National Semiconductor Strategy, announced in 2023, includes funding for a domestic SiC pilot line and packaging center, which could reduce reliance on imports and support local innovation. Additionally, the transition to 200mm SiC substrates is expected to improve cost efficiency and supply security, further driving market growth. Stakeholders in the automotive and industrial sectors will need to navigate supply chain challenges and qualification timelines to fully capitalize on the benefits of SiC technology.
