South Korea is moving to accelerate investment in the semiconductor capacity needed to supply the artificial-intelligence boom, with Samsung Electronics set to begin a $4.6 billion expansion of its chip manufacturing operations next month. For U.S. companies and investors watching the global AI supply chain, the project underscores Seoul’s effort to strengthen domestic production of advanced memory and other high-performance chips as demand for AI infrastructure surges.
On August 19, South Chungcheong Province approved a key urban-planning measure required for Samsung to expand its Onyang semiconductor campus in Asan, clearing the way for construction to begin in September.
Samsung plans to build a new manufacturing facility on a roughly 4.2 million-square-foot site within the campus. The project is designed to expand production of high-performance AI semiconductors, including high-bandwidth memory, or HBM, a critical component in advanced computing systems.
The investment is part of a broader push by South Korea to accelerate large-scale private-sector spending in strategic industries and reduce delays caused by permitting and other administrative procedures. The province said the Samsung project is the first to reach the construction stage among initiatives included in the government’s “Three Mega Projects for Korea’s Next Leap.”
The provincial government, Asan city and Samsung worked with relevant agencies to review documents and coordinate approvals in advance, allowing the urban-planning review to be completed more than a month earlier than originally scheduled.
The approval also represents the first investment-support case led by the Chungnam Advanced Strategic Industries Leap Task Force, which began operating in July.
“We will concentrate our administrative resources on quickly removing obstacles to corporate investment so that South Chungcheong can emerge as a hub for advanced strategic industries,” Hong Jong-wan, the province’s vice governor for administration, said.
The Samsung expansion comes as South Korea seeks to bring forward a much larger wave of investment in semiconductors and displays. On July 2, South Chungcheong signed investment agreements with Samsung Display, SK hynix and other companies covering a combined $155 billion in planned investment in the province.
The province has since launched a five-part investment-support program encompassing 30 initiatives designed to speed up those projects.
For U.S. investors and technology companies, the developments point to an increasingly investment-intensive race to build AI infrastructure, with advanced memory capacity emerging as one of the key constraints—and strategic assets—in the global semiconductor supply chain.
