(Image: SK ecoplant) SK hynix on June 29 unveiled a long-term investment plan totaling 1,100 trillion won, allocating 600 trillion won to the Yongin semiconductor cluster, 100 trillion won to its Cheongju manufacturing base, and 400 trillion won to a new semiconductor cluster in South Korea's southwest region. The company will accelerate th

SK Hynix said on June 29 it will spend KRW1,100 trillion (approx. US$710 ​billion) across three sites in South Korea over the coming decades, accelerating its Yongin cluster timeline by 12 years as it warned that even faster construction will not be enough to meet projected AI memory demand.

Samsung said on June 29 it will invest a combined KRW2,655 trillion (approx. US$1.72 trillion as of June 30, 2026) across its domestic operations, splitting the figure between continued buildout of its existing Pyeongtaek and Yongin semiconductor clusters and a fresh push into Korea's southwestern Honam region, where the bulk of the new money is aimed at memory capacity.

(Source: SK ecoplant) TEMC CNS has begun supplying Central Chemical Supply Systems (CCSS) to SK hynix, indicating that construction of the chipmaker's first fabrication plant (fab) at its Yongin Semiconductor Cluster has been completed and the project has entered the cleanroom installation phase. TEMC CNS said on June 26 that it ha

SK Hynix is racing to complete the first cleanroom at its massive Yongin Semiconductor Cluster in Gyeonggi Province, South Korea, by February 2027, ahead of rival capacity expansion timelines. The site's first fabrication facility will break from conventional flat-floor layouts, stacking production floors three levels high in a pioneering triple-deck fab design.

The global memory market is facing a structural supply-demand imbalance that shows little sign of easing. Micron's stronger-than-expected quarterly results have drawn fresh attention from investors and the technology industry, while the broader supply picture remains tight.

South Korea's government is in talks with Samsung Electronics and SK Hynix over a potential new phase of large-scale semiconductor investments, as the two chipmakers review plans that could include front-end fabrication plants and packaging facilities across the country's Honam and Chungcheong regions. Both companies say no final decisions have been made.
