In a significant move for the global semiconductor industry, the United States has decided to implement new restrictions affecting companies from South Korea, such as Samsung and SK Hynix. The measure aims to prevent China from accessing advanced technology in integrated circuit manufacturing, which could further strengthen its position in the technological arena.
End of the Temporary Exemption
Until last year, the U.S. Department of Commerce had granted a temporary exemption to several foreign semiconductor manufacturers with plants in China, allowing them to equip their facilities with American technology. However, this period of leniency has come to an end. From now on, any chip manufacturer operating in China will need to apply for a license from the Department of Commerce to be able to import machinery containing U.S. components or technologies.
This restriction no longer affects Intel, which sold its plant in Dalian, China, but it does pose a significant problem for Samsung and SK Hynix, two of the most relevant South Korean companies in the sector.
Implications for Samsung and SK Hynix
Both companies have plants in China that require advanced technology to remain competitive in a constantly evolving market. Samsung manufactures NAND Flash chips in Xian, while SK Hynix produces DRAM integrated circuits in Wuxi and NAND Flash in Dalian. The ban on sending state-of-the-art equipment to these plants may severely limit their production capacity.
Lithography machines, essential for semiconductor manufacturing, heavily rely on U.S. technologies. For example, ASML, one of the leading manufacturers of lithography equipment, uses technologies from the California-based company Cymer. This gives the U.S. considerable control over who can access this technology.
Licenses and Restrictions
The U.S. Department of Commerce has made it clear that it will not grant licenses aimed at expanding production capacity in China or modernizing existing technology. Although the U.S. administration has assured that it will facilitate the necessary licenses for foreign chip manufacturers to continue operating in their Chinese plants, the restrictions will begin to take effect in 120 days, providing companies with a short period to adapt to the new regulations.
The situation is critical for South Korean firms, as the inability to import advanced equipment could harm their capacity to supply cutting-edge chips to the distribution chain in China.
International Reactions
In response to these measures, a spokesman for China’s Ministry of Commerce stated that Beijing firmly opposes the restrictions imposed by the U.S. and will take necessary actions to protect the legitimate rights and interests of Chinese companies. This situation could further escalate tensions between the powers in the technology sector.
The South Korean government, aware of the challenges its companies face due to these restrictions, is negotiating with the United States to seek solutions that safeguard the activities of its companies in the Chinese market.
Conclusions
The recent U.S. restrictions on South Korea in the semiconductor sector underscore the growing competition between the United States and China in the technological field. As trade tensions escalate, the outcome of these policies will not only have an immediate impact on the companies involved but could also redefine the global technological landscape in the coming years.
