It is only a year ago that Japan decided to regulate the export of three core semiconductor materials.

Korea's vulnerability to manufacturing industry has been revealed, and companies have responded with diversification and localization of import lines.

It is a high-purity hydrogen fluoride gas for semiconductor manufacturing, which is a mass production of large domestic companies, that is, etching gas.

It is a so-called'five nine' product with a purity of 99.999%, which is less than the quality of Japanese ultra-high purity'twelve nine', but is expected to be put into some production processes.

In general, hydrofluoric acid, or hydrofluoric acid, is a product produced by Chinese small and medium-sized enterprises that is made from Chinese raw materials, and is already used in semiconductor and display manufacturing sites.

This year, the effect of localization is confirmed even though imports of hydrogen fluoride from Japan fell 86% from the same period last year.

On the other hand, another regulated item, photoresist and fluorine polyimide, increased imports from Japan a year ago as exports continued to continue.

[Dong Hoon Lee / CEO of Chemtros: (Japan Export Regulations) Previously, it was not easy to develop original technology, and it was very difficult to obtain an evaluation opportunity equivalent to that of advanced products (from large companies). The environment has changed due to very good conditions.]

However, there are still a lot of items that Japan can arbitrarily control for export at any time, except for the white list.

It is a cold reality that we have minimized the damage in the past year's struggle and have to prepare for further Japanese retaliation.
