Showa Denko Launches Mass Production of 6-inch SiC Single Crystal Wafers
March 28, 2022 | JCN NewswireEstimated reading time: 2 minutes
Showa Denko K.K. (SDK) has launched mass production of silicon carbide single crystal wafers (SiC wafers) with a diameter of 6 inches (150 mm), which are used as materials for SiC epitaxial wafers to be processed and installed into SiC-based power semiconductors (SiC power semiconductors).
SiC power semiconductor has excellent heat-resisting property and high withstanding voltage much better than those of conventional silicon-based power semiconductor, which is currently the mainstream of power semiconductors. SiC power semiconductor contributes to improvement in power module's energy efficiency and downsizing. Therefore, the demand for SiC power semiconductors is increasing rapidly in various fields, especially those for use in xEVs, railcars, and industrial equipment.
As an independent supplier of SiC epitaxial wafers, SDK has the global-top share in the market, and has been providing power-device manufacturers with Best in Class SiC epitaxial wafers. Therefore, SDK's SiC epitaxial wafers are highly acclaimed by power-device manufacturers in and outside Japan.
SDK has been considering in-house production of SiC wafers, which are used as main material for SiC epitaxial wafers, aiming to improve quality of our SiC epitaxial wafers and establish a stable supply system for them. From 2010 to 2015, SDK took part in "Novel Semiconductor Power Electronics Project Realizing Low Carbon Emission Society," which was hosted and entrusted by the Ministry of Economy, Trade and Industry and New Energy and Industrial Technology Development Organization (NEDO), as a member of the "Research and Development Partnership for Future Power Electronics Technology." Furthermore, in 2018, SDK took over SiC-wafer related assets of Nippon Steel & Sumitomo Metal Group (current Nippon Steel Group), and has been developing technologies for mass production of SiC wafers since then.
This time, SDK decided to launch in-house mass production of 6-inch SiC wafers because plural customers have adopted SDK's SiC epitaxial wafers made from our in-house produced 6-inch SiC wafers. On the other hand, SDK will continue purchasing SiC wafers from our partners in order to respond to rapidly growing demand for SiC epitaxial wafers for power semiconductors. Thus, SDK will diversify sources of SiC wafers, thereby establishing stable supply chain for SiC epitaxial wafers.
The Showa Denko Group aims to be a "Co-Creative Chemical Company" and contribute to the sustainable development of global society. Under this vision, SDK positions its operation to produce SiC epitaxial wafers, which contributes to efficient use of energy, as a next-generation business, and will allocate much of our business resources. The Group will continue contributing to the spread of SiC power semiconductors by maintaining "Best in Class" as its motto and continuing provision of high-performance and highly-reliable products.

The Right Approach: I Hear the Train A Comin'
04/25/2024 | Steve Williams -- Column: The Right ApproachTraining is often an afterthought in many organizations, and the longer a company has been in business, the more this seems to apply. Over the past couple of decades, it has been amazing to observe that the biggest offenders of this are the companies that overuse the sound bite, “Our most important assets are our people.” When you dig into the process and peel back the onion, their commitment to training is not commensurate with that statement.
