DuPont will build an extreme ultraviolet (EUV) photoresist production plant in Cheonan, South Korea by investing US$28 million. The material is used for optical wafer design during semiconductor manufacturing and the Japanese government has restricted exports of the material to South Korea for months.
The Ministry of Trade, Industry and Energy announced on Jan. 9 that Minister Sung Yoon-mo and DuPont president Jon Kemp reached the agreement in the Silicon Valley on Jan. 8 (local time). “We will work very closely with major clients in South Korea for EUV photoresist development and production,” the DuPont president said.
The Japanese government initiated the restriction in July last year. Since then, the ministry has kept in touch with DuPont for stability enhancement in the material, component and equipment industries.
