South Korea unveils $520 billion investment plan with Samsung and SK Hynix to expand memory chip dominance — plan includes four new fabs and HBM facilities, amid strong government support - Tom's Hardware

South Korea unveiled a $520 billion public-private investment plan on June 29, 2026, aimed at expanding its dominance in the global memory chip market through collaboration between Samsung Electronics... Read original →

South Korea’s $520 billion semiconductor push is a state-engineered bet to lock in generational leadership in memory. By fast-tracking four HBM- and EUV-focused fabs, Seoul intensifies demand for advanced photoresists, ultra-pure gases, and hybrid bonding equipment—forcing rivals in Taiwan, China and the U.S. into reactive cost spirals. While streamlined permitting cuts red tape, geographic concentration near Gwangju heightens supply chain fragility, especially if U.S.-Japan export controls throttle ASML’s EUV shipments. Micron will likely accelerate its Japan-based 2β node with Rapidus, while Yangtze Memory may pivot to differentiated NAND to avoid direct confrontation. Within 18 months, the battle over HBM4 standards will define market control—Seoul’s real gamble is that AI chip architectures won’t undergo radical disruption before its new capacity comes online.
