Showa Denko Concludes Long-Term Contract to Offer SiC Epitaxial Wafers for ROHM Co., Ltd.
TOKYO, Sep 13, 2021 – (JCN Newswire) – Showa Denko Sufficient.Sufficient. (SDK; TSE: 4004) has concluded a lengthy-timeframe offer contract with ROHM Co., Ltd. (ROHM), a Eastern semiconductor manufacturer offering highly efficient SiC energy semiconductors for the global market, to offer SiC epitaxial wafers for energy semiconductors (SiC epi-wafers) for plural years.
ROHM decided to withhold out this ling-timeframe contract as a consequence of the corporate appreciated excessive-quality and stable offer system of SDK’s SiC epi-wafers. ROHM continues constructing insist-of-the-artwork semiconductors, and therefore, this lengthy-timeframe contract will extra toughen technical cooperation between SDK and ROHM on improvement in qualities of SiC epi-wafers along with homogeneity in properties[1] and low density of surface defects[2].
SDK’s SiC epi-wafers, which were launched into the market in 2009, had been adopted by digital tool manufacturers as parts of a quantity of devices along with energy offer for servers of cloud computing programs, inverters for railcars and solar energy expertise programs, and converters installed in like a flash charging stands for EVs. SDK expects that its SiC epi-wafer alternate will develop extra within the marketplace for SiC energy devices which is anticipated to develop very powerful.
Because the very best honest manufacturer of SiC epi-wafers (estimated by SDK), and beneath a motto of “Finest in Class,” the Showa Denko Community will continue going through like a flash growth of the marketplace for SiC epi-wafers and offering the market with excessive-efficiency and highly-legit products, thereby contributing to the propagation of SiC energy semiconductors which assign energy with small energy loss and never more warmth expertise.
[1] “Homogeneity in properties” blueprint that homogeneity in doping of nitrogen which determines bodily property of wafer has been finished. SiC energy semiconductor is constituted of SiC doped with nitrogen. SiC energy semiconductor for excessive voltage requires homogeneous doping with small quantity of nitrogen.
[2] “Low density of surface defects” blueprint that the wafer has extraordinarily small numbers of surface defects per sq. centimeter of wafer surface. If a surface defect exists, electrical energy flows through that surface defect, and the chip can now not be extinct as energy tool. On the more than a couple of hand, SiC energy tool for gigantic present requires gigantic SiC chip. This skill that truth, low density of surface defects is necessary for success of excessive yields in manufacturing of energy devices. SDK’s 2nd expertise excessive-grade SiC epi-wafer (HGE-2G) has finished 1/2 or much less density of surface defects when put next to that of the principle expertise product (HGE).
