SK Hynix Starts Construction of Advanced Packaging Facility to Expand AI High-Bandwidth Memory Production
SK Hynix announced on April 22, 2026, that it has begun construction of a new advanced packaging center in Cheongju Technopolis, South Korea. The facility is designed to increase the company’s production capacity of high-bandwidth memory (HBM) modules, which are critical components for AI data centers and high-performance computing systems. This initiative reflects SK Hynix’s strategic focus on enhancing back-end semiconductor processes to meet the growing demand for memory solutions tailored to AI workloads Digitimes.
The new packaging hub will specialize in 3D packaging and chip stacking technologies. These processes enable the integration of multiple DRAM layers through through-silicon vias (TSVs), which improves data transfer rates and reduces latency. SK Hynix emphasized that this facility will support next-generation AI infrastructure by delivering memory products optimized for scalability and performance Digitimes.
Cheongju Technopolis was selected for the facility due to its proximity to SK Hynix’s existing manufacturing ecosystem and access to a skilled workforce. The location is expected to facilitate efficient operations and accelerate the scaling of advanced packaging production lines.
Industry analysts estimate that the new center could raise SK Hynix’s HBM packaging output by up to 40% within two years. This expansion aims to address the increasing bandwidth and capacity requirements of AI workloads, which have become a bottleneck in system performance. HBM’s vertically stacked architecture, combined with advanced packaging, offers faster data transfer rates and lower power consumption compared to conventional memory types Digitimes.
SK Hynix’s investment aligns with broader semiconductor industry trends prioritizing advanced packaging as a critical area for performance improvement. Competitors such as Micron and Samsung are similarly expanding their HBM technology capabilities to meet AI market demands. Experts note that enhanced packaging allows memory manufacturers to supply modules capable of handling large data flows with minimal latency, which is essential for AI accelerators, GPUs, and high-performance computing systems.
The facility will also support heterogeneous integration efforts, where multiple chip components are combined in a single package to optimize space and power efficiency. This approach is increasingly important for compact AI hardware designs Digitimes.
SK Hynix is a leading global manufacturer of memory chips, including DRAM and NAND flash. The company has invested heavily in HBM technology, which stacks multiple DRAM layers vertically and connects them with TSVs to achieve high bandwidth in a smaller footprint. HBM is particularly suitable for AI and high-performance computing due to its ability to deliver several times higher data transfer rates than traditional DDR memory while reducing board space.
The new packaging center will complement SK Hynix’s wafer fabrication facilities by focusing on assembly and testing stages. These stages are vital for ensuring the reliability and performance of HBM modules. By expanding packaging capacity, SK Hynix aims to alleviate supply chain constraints and accelerate production to meet growing customer demand.
SK Hynix has not publicly disclosed the total investment amount or the expected completion date for the Cheongju facility. However, industry observers expect the center to become operational by late 2027, with phased capacity increases following commissioning.
This development highlights the increasing role of advanced packaging in the semiconductor supply chain amid rising AI workload demands. By boosting its HBM packaging capacity, SK Hynix positions itself to capture a larger share of the AI memory market and contribute to the infrastructure supporting next-generation AI technologies.
