June 30, 2026 – SK Hynix has officially rolled out an ambitious long-term investment blueprint totaling 1,100 trillion Korean won, aiming to scale up its semiconductor manufacturing capacity across key regions in South Korea and strengthen its foothold in the global memory chip market amid surging industry demand.
The tech giant’s multi-billion-dollar investment initiative is strategically distributed across three core domestic zones, with adjusted construction timelines and targeted capacity upgrades to address the rapidly expanding global appetite for DRAM, NAND flash, and advanced HBM (High Bandwidth Memory) solutions.
Leading the investment plan is the Yongin semiconductor cluster, secured with a fixed capital injection of 600 trillion won for the development of four wafer fabrication facilities. In a major schedule acceleration to capture growing DRAM market demand, SK Hynix has drastically shortened the project’s completion timeline. Originally slated for full completion in 2045, the entire development project will now finish the construction of the first clean room for its fourth Yongin wafer fab (Phase 1) by 2033, cutting the construction period by 12 years to ramp up DRAM output ahead of schedule.
Cheongju, SK Hynix’s long-standing production hub, will receive a 100-trillion-won investment boost to upgrade and expand its operational capabilities. The allocated funds will be deployed for constructing new NAND wafer fabs, installing state-of-the-art production equipment, and advancing backend packaging technologies for high-end HBM products. This move is set to consolidate the firm’s competitiveness in NAND flash manufacturing while reinforcing its advanced HBM production ecosystem, a critical segment driving AI computing hardware development.
The remaining 400 trillion won of the total investment will be dedicated to new semiconductor projects in South Korea’s southwestern regions, focusing primarily on front-end manufacturing processes for memory chips. Preparatory work for the regional expansion will kick off immediately, though exact construction sites are yet to be finalized by the company.
During a post-announcement Q&A session, SK Hynix also disclosed flexible long-term development possibilities. The firm noted that overseas wafer fab construction could be added to its future development agenda if local infrastructure and semiconductor industry ecosystem requirements are fully satisfied. Final decisions on overseas expansion will be made comprehensively based on evolving global market trends and the company’s long-term business development needs.
