High-purity water ‘ultra-pure water’ is required for manufacturing semiconductors, etc.
Equipped with ultrapure water production facilities in each semiconductor manufacturing complex
Promote self-reliance of ultrapure water technology to prevent recurrence of hydrofluoric acid incident

Today (28th) is ‘Semiconductor Day’.
Japan’s export restrictions in 2019 reminded me that foreign-dependent technology can always be a pawn in a trade war.
Like Foshan in the past, there is water called ‘ultra-pure water’ among the things that our semiconductor companies are 100% dependent on foreign countries.
The work to localize it has begun.

Impurities in the semiconductor or display process lead to defective products.
So, when diluting chemicals or cleaning, high-purity water is required.
The water used at this time, with almost no impurities, is called ‘ultra-pure water’.
About 1 liter of ultrapure water is required to wash one 12-inch wafer.
Since a large amount of ultrapure water is required for the manufacturing process, each semiconductor plant complex has its own production facility.
This water is ultrapure water.
Both Samsung Electronics and SK Hynix depend on foreign countries for plant design and parts to produce this ultrapure water.
Most of them are Japanese companies.
Technological independence is being promoted to prevent ultrapure water manufacturing parts and equipment from becoming a strategic commodity in a trade war, such as in the recent Foshan incident.

The goal is to “completely localize ultra-pure water” by 2025, designing, constructing, and even operating an ultra-pure water production facility using parts developed by our company.
[박재현 / 한국수자원공사 사장 : 소재·부품·장비 분야의 국내 물 기업을 육성해서 초순수 기술의 국산화를 앞당기고자 합니다. 이를 통해서 K-반도체의 안정적인 생산과 수출에 기여하도록 하겠습니다.]
An ultrapure water demonstration production facility will also be built next year.
Domestic companies plan to test the quality by using the ultrapure water produced there for actual semiconductor manufacturing.
