NextFin News - On December 10, 2025, South Korea announced plans to consider the establishment of a 4.5 trillion won (approximately $3.1 billion USD) semiconductor foundry dedicated to strengthening its local chip manufacturing ecosystem. This decision was conveyed following a high-level meeting chaired by President Lee Jae Myung in Seoul, involving top executives from major chipmakers such as Samsung Electronics and SK Hynix, alongside government policymakers and industry experts. The foundry will focus on producing legacy 12-inch, 40-nanometer chips vital for automotive, data center, and other critical applications, a segment increasingly important due to rising demand for AI-capable semiconductors.
The initiative aims to counteract South Korea’s lag behind leaders like Taiwan Semiconductor Manufacturing Company (TSMC) in the logic chip sector, diversifying beyond the country's historical strength in memory chips. The project will be jointly funded by public and private entities, and consultations are ongoing with domestic foundry firms including the likes of DB HiTek. A noteworthy element includes an emphasis on developing domestic defense-related semiconductors to alleviate the heavy reliance on imports, which currently accounts for about 99 percent of supply, reflecting a broader national security imperative.
Industry Minister Kim Jung-kwan characterized the global semiconductor landscape as a geopolitical battleground, highlighting the intense competition across the US, China, Europe, and Japan for technological supremacy. As part of the governmental strategy, a special semiconductor committee under President Lee's direct oversight will coordinate national chip policies and initiatives. The government is also exploring legal provisions to prioritize domestic semiconductor procurement within critical infrastructure to enhance security resilience.
South Korea's semiconductor sector is pivotal to its economy, with Samsung Electronics and SK Hynix ranked among the world’s foremost memory chip producers. However, the foundry initiative represents a critical strategic pivot toward advancing local capabilities in designing and manufacturing logic chips, particularly those optimized for artificial intelligence applications. The increasing prevalence of AI-driven technologies across sectors generates substantial demand for specialized chips that traditional memory chip makers have not fully addressed.
This planned foundry underscores a trend among semiconductor-reliant nations to vertically integrate and locally secure supply chains, reducing exposure to international disruptions that have been magnified since 2020. Industry data shows that the global semiconductor market is projected to surpass $1.5 trillion by 2030, with AI-focused chip segments growing at double-digit CAGR, underscoring the commercial and strategic impetus for South Korea’s enhanced foundry capacity.
By investing in the fabrication of mature node chips such as 40nm, which remain critical for automotive electronics and certain industrial applications, South Korea aims to fill a niche underserved by leading-edge foundries that focus more on sub-10nm geometries. This niche focus allows the country to leverage existing manufacturing expertise while building a foundation to evolve capabilities for more advanced chip fabrication.
From a geopolitical perspective, South Korea’s strategy aligns with broader trends where semiconductor industries evolve into instruments of economic security and technological sovereignty. Given the escalating global tensions and trade restrictions impacting chip supply chains, the U.S. President and allied governments have prioritized supporting domestic chip production. South Korea's initiative is poised to complement these alliances by reinforcing East Asia’s chip supply base.
Looking forward, this strategic investment may catalyze advancements in South Korea’s fabless chip design ecosystem, stimulate R&D investments in AI-specific chip architectures, and attract foreign partnerships and technology transfers. The establishment of the semiconductor special committee indicates a coordinated policy approach that may accelerate talent development, incentivize innovation, and enhance regulatory frameworks to sustain competitiveness.
However, challenges remain, including managing the substantial capital expenditure required for foundry operations, ensuring scale economies, and navigating global supply chain complexities. The outcome will depend heavily on the successful collaboration between government agencies and the private sector, along with the agility to adapt to fast-emerging AI chip technologies and market shifts.
Overall, South Korea’s $3.1 billion foundry plan reflects a forward-looking strategic endeavor to secure its semiconductor future amid heightened global competition. It is an assertive step in mitigating risks of over-dependency, expanding technological depth beyond memory chips, and aligning industrial capabilities with the surging demand for AI and defense-grade semiconductors.
