Resonac

The Resonac Group was established in January 2023 as a result of the integration of the Showa Denko Group and the Showa Denko Materials Group (former Hitachi Chemical Group). The Group’s annual sales of semiconductor and electronic materials amount to approximately 340 billion yen. The Group is recognized for its extensive lineup of semiconductor materials for back-end processes, which have top market share globally. The integration of the two companies has enabled the Resonac Group to make material design and development in-house from raw materials through to finished goods. The new trade name “RESONAC” was created as a combination of two English words, namely, the word “RESONATE” and “C” from the first letter of CHEMISTRY. The Resonac Group actively leverages its co-creative platform to accelerate technological innovation with semiconductor manufacturers, materials manufacturers, and equipment manufacturers in Japan and across the globe.
