Showa Denko has concluded a two-year contract including optional extension clauses with Infineon Technologies AG (Infineon), a German semiconductor manufacturer providing semiconductor solutions for automotive and industrial use worldwide, to sell SiC materials for power semiconductors and cooperatively develop SiC materials technology.

SDK expects the contract will enable Infineon to apply SDK SiC materials to various power semiconductor products and the two companies to accelerate improvement in quality of products by bringing together the two companies' knowledge.

Due to the homogeneity in properties and low density of surface defects[, SDK SiC epi-wafers materials, which were launched into the market in 2009, have been adopted by electronic device manufacturers as parts of various devices including power supply for servers of cloud computing systems, inverters for railcars and solar power generation systems, and converters installed in quick charging stands for EVs.

As the largest independent manufacturer of SiC epi-wafers (estimated by SDK), and under a motto of "Best in Class," the Showa Denko Group will continue coping with rapid expansion of the market for SiC epitaxial wafers and providing the market with high-performance and highly-reliable products, thereby contributing to the proliferation of SiC power semiconductors.
