Four U.S. companies signed on to pour roughly $2 billion into South Korea's semiconductor and clean-energy buildout this week, filing formal investment declarations in Washington that tie American industrial muscle directly to Seoul's push to dominate global chipmaking. Air Products, Axcelis Technologies, Corning and Pacifico Energy each committed to projects anchored in Pyeongtaek and along South Korea's southern coast, betting that the country's AI and chip ambitions will keep growing for years to come.
The declarations were filed at an investment ceremony and investor roundtable held at the Willard Hotel, according to BiGGo, with South Korea's Ministry of Trade, Industry and Energy and the Korea Trade-Investment Promotion Agency jointly announcing the roughly 2.7 trillion won package. The four companies filed declarations spanning offshore wind, semiconductor materials and equipment, and advanced materials for displays, per the same report.
Air Products Expands Its Korean Operations
Air Products, an industrial gas company, is expanding its South Korean operations. As reported by KED Global, the company signed a supply contract and will bring facilities online in phases through 2030, making Pyeongtaek a major site for its global electronics operations.
Air Products will build dedicated industrial gas supply infrastructure at that next-generation semiconductor hub, including ultra-high-purity gas facilities and rare gas equipment for fine semiconductor processing, according to BiGGo's report. The investment marks the company's largest since it entered South Korea, the outlet noted — a striking reversal for a business that was actively shopping its Korean operations not long ago.
Axcelis Deepens Its Only Manufacturing Base Outside The U.S.
Axcelis Technologies, a semiconductor equipment maker, will expand its ion implanter manufacturing facility in Pyeongtaek — the company's only manufacturing base outside the United States, and one that has produced ion implanters domestically since 2021, per BiGGo. Businesskorea reports that the company now plans to build the plant into a broader technological innovation hub incorporating research and development alongside technical training.
South Korea's government expects the expansion to strengthen the country's position as an Asia-Pacific export hub for ion implanters, according to BiGGo's account of the declaration. The move builds directly on South Korea's long-term semiconductor blueprint: a 622 trillion won, or roughly $470 billion, mega-cluster stretching across Gyeonggi Province from Pyeongtaek to Yongin through 2047, as reported by the South China Morning Post.
Corning And Pacifico Energy Round Out The Package
Corning, a glass, ceramics and optical materials company that has invested in South Korea for more than 50 years since 1973, filed its own declaration to pursue production facility upgrades in Asan, South Chungcheong Province, per BiGGo. The company plans to accelerate installation of advanced materials equipment for next-generation mobile devices and semiconductors there. Businesskorea and SBS News also note that Corning's Asan facilities serve display-glass and semiconductor-related applications, underscoring the plant's dual role serving both consumer electronics and chip packaging.
Pacifico Energy, an energy infrastructure company with existing projects in the United States, Japan and Vietnam, will develop a 3.2 GW offshore wind farm in waters off Jindo, South Jeolla Province, and Gwangju. Businesskorea reports the Jindo investment specifically funds the 990 MW Manho and 1.8 GW Jindo Baram developments — the second and third phases of the 3.2 GW Jindo cluster, which the outlet describes as one of the largest offshore wind projects in the Asia-Pacific region. The company previously developed the 7.65 GW “Gigawatt Ranch” data center campus project in the U.S., which was acquired by Amazon to provide gas-fired generation for hyperscale AI facilities — a precedent for pairing generation directly with high-density tech sites.
Tariff Talks Loom Over The Ceremony
The Washington declaration landed amid live trade friction. Per Benzinga, U.S. Commerce Secretary Howard Lutnick was evaluating new semiconductor tariffs, while South Korean Industry Minister Kim Jung-kwan discussed ways to expand investment cooperation between the two countries. Kim said the four companies expressed trust in and support for South Korea's foreign investment policies and strong agreement with its semiconductor investment direction, according to BiGGo.
Kang Kyung-sung, president of KOTRA, said the investment is directly connected to semiconductors, AI, data centers and physical AI, and added that advanced industry investment can expand clean energy supply for AI data centers while strengthening South Korea's domestic semiconductor materials and equipment supply chain, per BiGGo's reporting. The South Korean government assessed the package as demonstrating investment cooperation between the two countries built on mutual trust, the outlet reported. The package was reported at roughly $2 billion, according to Investment Monitor.
A San Francisco Sidebar For Korean Startups
Alongside the corporate declarations, the Ministry of Trade, Industry and Energy hosted a Korea-U.S. CVC/VC forum in San Francisco that connected eight South Korean startups working in AI, autonomous driving and advanced materials with local investors. The startups presented their business models and growth visions to venture and corporate venture capital firms and explored cooperation through one-on-one consultations, BiGGo reported. Separately, Kim made a similar pledge at the Washington investment roundtable.
The ministry said it plans to continue follow-up discussions with U.S. investors and find concrete measures for substantive investment cooperation going forward, according to BiGGo's report.
