Showa Denko Concludes MOU with SK. to Give Consideration to a Plan to Cooperatively Produce High-Purity Gases for Semiconductors in North America

Showa Denko K.K.(SDK) and SK Incorporated concluded a memorandum of understanding (MOU) to give consideration to a plan to start cooperative work to produce high-purity gases, which are used in semiconductor production processes, in North America.

SDK and SK Materials, which is an in-house independent company of SK Incorporated and produces high-purity gases for semiconductors, will start to give consideration to a plan to cooperatively produce high-purity gases for semiconductors in North America. In the global market for high-purity gases for semiconductors, SDK has the top share of the etching gas market, and SK Materials has the top share of the cleaning gas market and deposition gas market. Thus, the two leading companies in the high-purity gas industry are now aiming to expand their business in the US cooperatively.

SDK and Microwave Chemical Start Joint Development of Microwave-based Chemical Recycling Technology to Directly Transform Used Plastic into Basic Chemical Feedstock

Showa Denko (SDK) and Microwave Chemical have started joint development of a new microwave-based chemical recycling technology to directly transform used plastic into basic chemical feedstock.

SDK and Microwave Chemical will aim to develop a technology that decomposes used plastic containers and packaging by irradiating microwave, thereby producing basic chemical feedstock such as ethylene and propylene. By the end of this year, the two companies will study conditions for formation of product through microwave heating, search for catalysts to improve the yield of targeted components, and try to optimize conditions and processes for decomposition to establish basic technology.

JDI and Idemitsu developed Poly-OS, a poly-crystalline oxide semiconductor applicable to a wide vriety of displays

Japan Display (JDI) and Idemitsu Kosan have successfully co-developed an innovative poly-crystalline oxide semiconductor, Poly-OS, for use in a wide variety of displays, including wearable devices, smartphones, metaverse devices such as VR, Notebook PCs, and large-display TVs.

By integrating Idemitsu Kosan's newly developed proprietary poly-crystalline oxide semiconductor material and JDI's proprietary backplane technology, the new Poly-OS semiconductor contributes significantly to improving display performance by achieving both high mobility and low off-leak current on Gen 6 mass production lines. Poly-OS can also be deployed to large-size Gen 8 lines and above, significantly reducing display manufacturing costs.
