South Korea goes for Japanese liquid hydrogen fluoride meant for Samsung Electronics and SK Hynix.

According to reports the Japanese government has allowed the export of liquid hydrogen fluoride because it was judged that Japan would be disadvantaged by disputes in the World Trade Organization (WTO) if the situation of not allowing exports was prolonged.

Alles Europa news reports that Of the three semiconductor-related materials that the Japanese government tightened export controls in July, several Korean reported that they allowed to export liquid hydrogen fluoride.

After stricter export control, resist (photosensitive material), polyimide fluoride, and gaseous hydrogen fluoride have already been exported, but in fact, this is the first export license for liquid hydrogen fluoride, which is indispensable for semiconductor production.


According to reports, the Japanese government recently reported to the Korean side that it has allowed the export of liquid hydrogen fluoride, which has been filed by Stella Chemifa , a major fluorine compound, to Korea. It is for Samsung Electronics and SK Hynix, the world’s leading semiconductor memory.

Alles Europa news reports that In July, the Japanese government exported three items: fluorinated polyimide, which is the material for organic EL panels for smartphones, high-quality resist applied to semiconductor silicon wafers, and hydrogen fluoride used for cleaning semiconductor manufacturing processes. Changed to ask for individual permission.

Hydrogen fluoride has issued an export license for gaseous etching gas, but has not allowed export of high-purity liquids used in the production of cutting-edge semiconductors.

Also the South Korean government strongly opposed the stricter export control by the Japanese government, and decided to abolish the Japan-Korea Military Information Comprehensive Protection Agreement (GSOMIA).

They claim that GSOMIA will not be extended unless Japan withdraws the measure by midnight on the 23rd of the expiration date. Based on the Japanese government’s license to export liquid hydrogen fluoride, the Korean side may soften its attitude toward GSOMIA.


Japanese manufacturers hold over 70% of the global market for liquid hydrogen fluoride. Due to its nature, long-term inventory was considered impossible, and if it could not be exported for a long time, it could have a major impact on global semiconductor production.
