Showa Denko K.K. has concluded a long-term supply contract with ROHM Co., Ltd. (ROHM), a Japanese semiconductor manufacturer providing highly efficient SiC power semiconductors for the global market, to supply SiC epitaxial wafers for power semiconductors (SiC epi-wafers) for plural years.

 

ROHM decided to conclude this ling-term contract because the company appreciated high-quality and stable supply system of SDK's SiC epi-wafers. ROHM continues developing state-of-the-art semiconductors, and therefore, this long-term contract will further strengthen technical cooperation between SDK and ROHM on improvement in qualities of SiC epi-wafers including homogeneity in properties and low density of surface defects.

 

SDK's SiC epi-wafers, 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. SDK expects that its SiC epi-wafer business will grow further in the market for SiC power devices which is expected to grow very much.

 

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 epi-wafers and providing the market with high-performance and highly-reliable products, thereby contributing to the propagation of SiC power semiconductors which save energy with small power loss and less heat generation.
