South Korea plans $518 billion semiconductor hub for AI demand
Samsung Electronics and SK Hynix have announced plans to invest a combined 800 trillion won, about $518 billion, in a new semiconductor manufacturing hub in South Korea’s southwest.
The two companies, which together produce around two-thirds of the world’s memory chips, will each build two new fabrication plants outside their existing manufacturing base in Gyeonggi Province.
Samsung’s new facilities are planned for the city of Gwangju, with several possible sites under consideration, including land linked to a military air base planned for relocation.
The investment responds to rising demand for memory chips used in AI data centres, industrial robotics and autonomous vehicles. Existing semiconductor facilities in Gyeonggi Province are expected to face capacity pressure sooner than previously projected.
South Korea’s government is also linking the project to a broader strategy to build a nationwide semiconductor ecosystem. Existing hubs in the Southeast are expected to expand chip component and material production. At the same time, the central Chungcheong region will focus on chip packaging, and data centres will be developed across the country.
The project also supports the government’s goal of spreading major technology investment beyond the Seoul metropolitan area, where much of the country’s semiconductor industry has historically been concentrated.
Why does it matter?
The planned investment shows how AI demand is driving long-term semiconductor capacity expansion at a national scale. Memory chips are central to AI data centres and high-performance computing, and Samsung and SK Hynix remain two of the most important suppliers in the global market. South Korea’s decision to link new chip fabrication with regional development also shows how AI infrastructure is becoming part of broader industrial and economic planning, not only technology strategy.
