SK Inc. materials is a global leader in specialty gas and materials for semiconductors and displays. The unwavering research and development (R&D) efforts made by the company came to fruition in 2001 when SK Inc. materials became the first company in Korea to successfully produce nitrogen trifluoride (NF3) gas locally.

NF3 is a specialty cleaning gas which is used to remove residue in chambers during the production process of semiconductors and displays. SK Inc. materials is solidifying leadership as the number one player in the market with more than 40 percent of the global market share of NF3. The company is unmatched with a product portfolio that includes the production and distribution of tungsten hexafluoride (WF6), monosilane (SiH4), dichlorosilane (SiH2Cl2), and disilane (Si2H6). SK Inc. materials is the largest global producer of WF6, and the second largest producer of SiH4 worldwide.

Since joining SK Group in February 2016, SK Inc. materials has added a diverse array of semiconductor materials such as industrial gas, precursors, etching gas, and photoresist (PR) to generate synergy. The company will continue to develop next-generation products and innovate production processes to leap forward to become a global top-tier materials platform company.
