Infineon Technologies AG and Wolfspeed have signed a multi-year agreement for the supply of 200-millimetre silicon carbide (SiC) wafers, transitioning their existing supply arrangement from 150 mm to 200 mm substrates. The agreement supports Infineon’s shift to 200 mm SiC manufacturing and strengthens supply chain resilience as demand for power semiconductors grows across electric vehicles, renewable energy systems and AI data centre infrastructure.
“Silicon carbide is at the heart of the energy transition, and securing a high-quality, resilient supply of 200-millimeter substrates is essential to delivering on our customers’ long-term commitments,” said Alexander Gorski, Chief Operations Officer at Infineon. “This agreement further broadens our strong supply base for our 200-millimeter high-volume manufacturing, building on a 20-year supply relationship between our two companies. It strengthens supply chain security for our customers and provides additional flexibility and scalability to support Infineon’s future growth.”
AI datacenters are beginning to emerge as a significant demand driver for SiC power semiconductors. Power conversion efficiency across the datacenter power chain is a direct operating cost consideration for hyperscalers managing infrastructure at scale. The switching efficiency and thermal performance of SiC make it a technically suitable option for specific power conversion stages where silicon reaches its practical limits. Together with growing SiC adoption across electric vehicle drivetrains, solar inverters and industrial motor drives, these trends support a strong long-term outlook for high-quality 200-millimeter SiC substrates.
The transition to 200-millimeter SiC wafers delivers large manufacturing economics compared to 150-millimeter production. Larger wafer diameter increases usable die area per wafer, reduces per-unit substrate cost, and improves overall manufacturing efficiency. Infineon operates a multi-source SiC substrate strategy to maintain supply chain flexibility and quality across its global manufacturing network, including its world-class 200-millimeter SiC fab in Kulim, Malaysia, which is designed to be the world’s largest and most competitive silicon carbide manufacturing facility.
Infineon Technologies AG is a global semiconductor leader in power systems and IoT. Infineon drives decarbonization and digitalization with its products and solutions. The Company had around 57,000 employees worldwide (end of September 2025) and generated revenue of about €14.7 billion in the 2025 fiscal year (ending 30 September). Infineon is listed on the Frankfurt Stock Exchange and in the USA on the OTCQX International over-the-counter market.
