According to Korean media reports, after the Japanese government restricted the export of advanced semiconductor materials such as hydrogen fluoride, photoresist, and fluorine-containing polyimide to Korea, SK hynix's semiconductor factory in Wuxi, China,has completely replaced Japanese products with hydrogen fluoride produced in China.

The report also pointed out that Samsung Electronics and SK Hynix engineers responsible for material development are conducting analysis of hydrogen fluoride samples produced in Korea, and Samsung Electronics has begun to use alternative products.

According to the report, Samsung Electronics and SK Hynix are progressing faster than expected in the search for replacement of hydrogen fluoride produced in Japan. It is expected that the Japanese products will be completely replaced by the end of the year.
