The memory that feeds AI accelerators has been packaged almost entirely in Asia. SK Hynix is changing that in Indiana. The company is building a $3.87 billion advanced packaging and R&D complex in West Lafayette, the first U.S. facility for packaging high-bandwidth memory, the stacked DRAM that sits next to the GPUs in AI servers.
Project Scope. The plant spans a 133-acre site near Purdue University, chosen for its proximity to the school’s semiconductor research and talent. Site work and grading began in early 2026, following building permits for the foundations of the manufacturing facility, an office building and a utility plant. Mass production is targeted for the second half of 2028. The project is expected to generate thousands of direct and indirect jobs, and it leans on a mix of company investment and federal incentives aimed at reshoring chip capacity.
Why It Matters. Packaging is the quiet chokepoint in the AI hardware chain. The U.S. has poured money into front-end wafer fabs, but the advanced packaging that turns wafers into HBM stacks stayed overseas, a gap no amount of domestic wafer capacity could close on its own. SK Hynix’s plant addresses that directly. Sited next to Purdue, it ties a major manufacturer to a research university, the kind of cluster policymakers have tried to engineer with CHIPS-era funding. For the Midwest, it’s an anchor in the emerging semiconductor corridor running through Ohio and Indiana.
