SK Hynix Approves $5.1B Investment to Accelerate HBM Packaging Capacity
SK Hynix has approved a 7.09 trillion won (approx. $5.1 billion) investment for its P&T7 advanced packaging and testing facility in Cheongju, South Korea. This funding is part of a larger 19 trillion won project and aims to shorten cleanroom setup times to accelerate HBM production. The investment addresses a critical bottleneck in the AI hardware supply chain by expanding advanced packaging capacity for High Bandwidth Memory (HBM). As demand for AI chips surges, securing packaging and testing throughput is vital for maintaining market leadership. The P&T7 facility spans 230,000 square meters, featuring 150,000 square meters of cleanroom space. This includes 60,000 square meters dedicated to Wafer-Level Packaging (WLP) lines and 90,000 square meters for Wafer Testing (WT) lines.
## BACKGROUND
High Bandwidth Memory (HBM) is a 3D-stacked DRAM technology that offers massive throughput, making it essential for AI accelerators and high-performance computing. Wafer-Level Packaging (WLP) is an advanced packaging method where components are attached to the integrated circuits while still in wafer form, streamlining the manufacturing process. Major manufacturers like SK Hynix, Samsung, and Micron are racing to expand HBM capacity to meet unprecedented demand from the AI sector.
