‘Warning Lights’ Over Semiconductor Concentration Concerns - Businesskorea

Recent developments in South Korea's semiconductor industry highlight growing concerns over industry concentration and supply chain security. As the global semiconductor sector becomes increasingly co... Read original →

South Korea’s semiconductor concentration is triggering systemic vulnerabilities. Technologically, the U.S.-Japan-South Korea AI memory alliance accelerates HBM3E adoption but deepens reliance on American EDA and Japanese equipment, eroding domestic stack resilience. Regulatory shifts—export controls and subsidy clawbacks—will inflate overseas fab costs for Samsung and SK Hynix while forcing inefficient supply chain duplication. In response, TSMC may expand advanced packaging in the West, while China doubles down on Chiplet and RISC-V to bypass IP blockades. Over the next 12–24 months, the industry will fragment into ‘sovereign tech blocs,’ driving redundant capacity investments and looming oversupply, especially in mature nodes. Without rebuilding indigenous materials and equipment capabilities, South Korea’s manufacturing dominance could crack by 2027 despite its current account surplus.
