Infineon adds SK Siltron CSS as SiC wafer supplier
Infineon Technologies has extended its supply chain in a deal with silicon carbide (SiC) supplier SK Siltron CSS for 150mm wafers.
Under the agreement, SK Siltron CSS will provide Infineon with 150mm SiC wafers and support Infineon’s expansion to 200mm wafers. Infineon is building 200mm SiC lines at Villach in Austria and Kulim in Malaysia that is expected to start operation later this year..
Infineon has already signed a multi-year supply and cooperation agreement with Resonac (formerly Showa Denko) for 150mm SiC wafers and transitioning to 200mm. It also has a 200mm wafer deal with Coherent.
Producing larger SiC wafers is difficult as the material is as hard as diamond but larger wafers help reduce the cost of SiC MOSFETs for high voltage electric vehicles and renewable energy applications.

“For Infineon, supply chain resiliency is about implementing a multi-supplier strategy and thriving in times of adversity to create new growth opportunities and drive decarbonization,” said Angelique van der Burg, Chief Procurement Officer at Infineon.
“We are excited to partner with SK Siltron CSS to serve the growing SiC demand of our broad customer base with new energy-efficient and top-quality products, matching the highest standards in the SiC market.”
“With decades of experience in silicon carbide materials and manufacturing, we bring unparalleled knowledge to our sustainably manufactured compound semiconductor solutions. This wealth of experience is a cornerstone in our partnership with Infineon,” said Jianwei Dong, Ph.D., CEO of SK Siltron CSS. “This long-term supply agreement marks the synergy of our extensive expertise and Infineon’s vision to make life easier, safer and greener for generations to come.”
SK Siltron CSS is part of the SK Group, which also includes SK Telecom and memory maker sk Hynix, and is second to Samsung in Korea.
