South Korea Announces 19 Billion Dollar Semiconductor Support Package to Counter US CHIPS Act and Chinese Competition

Background

South Korea's semiconductor industry, built on decades of government-industry partnership, massive capital investment, and technology absorption strategies, is one of the few areas where a non-US, non-European economy has achieved global leadership in a technology category of strategic significance. Samsung Electronics and SK Hynix together control approximately 70 percent of the global DRAM memory market and more than 60 percent of NAND flash memory production. Samsung is also one of only three companies in the world capable of manufacturing at the most advanced logic chip nodes below 5 nanometres, competing with Taiwan's TSMC and Intel in the US for foundry customers requiring the highest-performance process technology. This industry position has made South Korea a significant prize in the global semiconductor competition between the United States and China, with Washington seeking Korean chipmaker participation in US-based fabrication through the CHIPS and Science Act incentive framework, and Beijing applying economic and diplomatic pressure to maintain Korean suppliers' continued access to the Chinese market, which absorbs substantial shares of Samsung and SK Hynix output. The US CHIPS Act's guardrails, which restrict companies receiving US subsidies from expanding certain China operations, have created significant compliance complexity for South Korean chipmakers that have built substantial China manufacturing footprints over two decades of market development. The Chinese market's importance to Korean chip companies has simultaneously made them vulnerable to Chinese regulatory action and export restriction threats if South Korea aligns too closely with US technology restriction policies.

The Support Package

The 19 billion dollar package announced by South Korea's Ministry of Trade, Industry and Energy on October 14, 2026 is structured across four categories over a five-year implementation period. Direct cash grants of 6 billion dollars are reserved for companies constructing or expanding advanced chip fabrication facilities in South Korea, with the grant covering 15 percent of capital expenditure for facilities producing chips at 3 nanometres or below. A new semiconductor investment tax credit scheme, modelled on the US CHIPS Act's 25 percent investment credit, will apply to all advanced semiconductor capital expenditure, including back-end packaging and testing facilities that have been prioritised as a supply chain vulnerability since the COVID disruptions. Infrastructure commitments totalling 4 billion dollars over five years will develop two new semiconductor industrial clusters in Gyeonggi Province, providing pre-built factory space, water and power infrastructure capable of supporting multiple wafer fabrication facilities, and workforce training centres linked to university semiconductor engineering programmes. Research and development grants of 2 billion dollars target next-generation memory architectures and 2-nanometre logic process development, addressing the innovation pipeline that determines competitive position beyond the current generation of production technology. Additionally, the Korean government has committed to maintaining the bilateral negotiating channel with the US Commerce Department that produced an initial guardrail exemption for Korean chipmakers' China operations in 2024, and has received a US commitment to apply the exemption to the new facility investments covered by the Korean package.

• 6 billion dollar direct grants for advanced fab construction at 3nm and below.
• 25% semiconductor investment tax credit for all advanced capex including packaging and testing.
• 4 billion dollar infrastructure investment for two new semiconductor clusters in Gyeonggi Province.
• US guardrail exemption maintained for Korean chipmakers' existing China operations.

Competitive and Geopolitical Context

South Korea's semiconductor support package arrives in a competitive environment where the scale of government intervention has reached levels that strain normal trade law frameworks. The US CHIPS Act committed 52 billion dollars to semiconductor manufacturing and R&D, producing new or expanded wafer fabs from Intel, TSMC, Samsung, and Micron in Arizona, Texas, Ohio, and New York. Japan's Rapidus programme, backed by 13 billion dollars in government support, is attempting to establish a 2-nanometre logic chip capability by 2027. The European Chips Act has committed 43 billion euros to European semiconductor production, though actual new manufacturing investment has progressed more slowly than initially projected. China's state-supported semiconductor industry is absorbing an estimated 40 to 50 billion dollars per year in combined government grants, loans, and procurement preferences, advancing domestic capabilities in mature nodes and beginning to approach competitive levels in some memory categories. Against this subsidised competitive landscape, South Korea's 19 billion dollar package is large in absolute terms but modest relative to the scale of investment being directed into chip manufacturing by the United States and China. Korean industry analysts note that Samsung and SK Hynix's competitive position ultimately depends on continued technology leadership and execution excellence in manufacturing rather than on subsidy levels, but that government support has become a necessary minimum condition for companies to sustain the capital expenditure levels that technology leadership requires. The 2-nanometre logic race between Samsung and TSMC will be the defining competitive test of the next three years, with Samsung having committed to beginning customer production in fiscal year 2027 while TSMC has targeted 2025 for its leading customers.
