Showa Denko K.K. (SDK) has decided to establish its subsidiary’s second factory producing high-purity gases for electronics in Shanghai. Shanghai Showa Electronics Materials (SSE), which is SDK’s wholly owned subsidiary producing high-purity gases for electronics, will establish new facilities to produce high-purity octafluorocyclobutane (C4F8) gas.
The Showa Denko Group is already producing high-purity C4F8 at its Kawasaki Plant and SSE’s first factory in Shanghai. The new facilities in Shanghai will be designed to produce 600tpy of high-purity C4F8. Operations are expected to begin in the second half of 2021.
As the market for semiconductor chips in Taiwan is expected to expand, SDK’s subsidiary Taiwan Showa Chemicals Manufacturing will also establish a new facility to produce 150tpy of high-purity C4F8. This new facility is scheduled to start up in 2020.
High-purity C4F8 is a specialty fluorogas used for etching and other micromachining processes. Due to expansions in information communication technologies, including 5G mobile technology, and the Chinese government’s policies on these high-technology industries, the market in China for semiconductor chips and display panels is growing strongly.
