Samsung breaks ground on HBM packaging plant in Asan in $34 billion bet on AI memory

Samsung Electronics broke ground on Thursday (November 12, Korea time) on a new high-bandwidth memory (HBM) advanced packaging plant in Asan, South Chungcheong Province, investing 6 trillion won (about $4.48 billion) in the facility, with about 40 trillion won more in advanced equipment investment to follow — roughly 46 trillion won (about $34 billion) in total. The new production line is scheduled to begin operations in June 2028, a year earlier than initially planned. South Korean President Lee Jae Myung and Samsung Electronics chairman Lee Jae-yong attended the ceremony.

Expanding for AI server memory demand

Samsung said the new plant will have three floors of clean-room space covering about 31,000 square metres, dedicated to packaging HBM chips for AI servers. As demand for high-bandwidth memory from AI data centres surges, HBM has become one of the most sought-after chip products in the world; bringing the start date forward by a year is aimed at securing supply share in the next generation of AI memory. Lee said at the ceremony that the Asan site "will become a core base for advanced HBM packaging".

Part of South Korea's 'mega projects'

The expansion is part of investment plans Samsung affiliates announced in July, and forms part of the South Korean government's "mega projects" covering semiconductors, physical AI and AI data centres, for which it has tapped Samsung, SK Hynix and other companies. Analysts see advanced packaging as a competitive battleground on par with advanced process technology, since packaging capacity determines how fast HBM can ship.

What to watch next

Once the plant starts up in June 2028, Samsung's HBM capacity will rise sharply; the market will watch whether its next-generation products clear customer qualification on schedule, and how the government's mega projects drive further industry investment.
