SK Hynix Commences Construction of Indiana Advanced Packaging Facility to Bolster US HBM Production

SK Hynix has reportedly broken ground on a new advanced memory packaging facility in West Lafayette, Indiana, that should boost the supply of US-made high-bandwidth memory (HBM), a critical component in high-end AI accelerators from companies like Nvidia and AMD. The construction commencement represents a significant investment in US semiconductor manufacturing capabilities and comes amid increasing efforts to build domestic supply chains for critical technologies.

Unlike standard memory used in consumer devices, HBM requires specialized packaging and test services to stack multiple DRAM layers—typically 8 to 12—to form a single high-performance module. Currently, most HBM memory is manufactured in Korea by Samsung and SK Hynix, with Micron being the United States' primary domestic source of advanced memory products.

The Indiana facility, expected to cost nearly $4 billion to build, will address growing demand for US semiconductor manufacturing capacity. According to industry reports from South Korean newspaper the Herald Economy, SK Hynix has notified local officials that construction of the facility's foundation is now underway, with vertical construction slated for later this year. The facility is expected to be completed in late 2027, with full-scale operations likely beginning in the second half of 2028.

This timing coincides with the anticipated market introduction of HBM4E memory, beginning with Nvidia's Rubin Ultra platform. The SK Hynix Indiana plant will include not only manufacturing capabilities but also an R&D facility where the company will develop future generations of memory technology.

"This investment represents SK Hynix's commitment to supporting the growing AI ecosystem in the United States," said a company representative in a statement. "By bringing advanced packaging capabilities to Indiana, we can better serve our US-based customers while contributing to the development of a more resilient semiconductor supply chain."

The construction of the Indiana facility occurs alongside similar efforts by other major semiconductor companies to establish US manufacturing presence. TSMC began production at its Arizona fab early last year, and companies like Nvidia, Apple, and AMD have subsequently announced plans to produce chips in the US. However, gaps in the US semiconductor ecosystem have created challenges, with some chips produced at TSMC's US facilities—particularly Nvidia's Blackwell GPUs—requiring shipment to Taiwan for final integration before returning to the US.

To address these gaps, Amkor Technology is developing a $7 billion, 750,000 square foot facility with advanced packaging capabilities in the US. Construction on Amkor's facility is expected to be completed in mid-2027, with production beginning in early 2028—coincidentally aligning with the timeline for SK Hynix's HBM factory. While SK Hynix will need advanced packaging capabilities to convert DRAM into HBM, the specific provider for these services has not yet been determined.

Intel's Foundry division has also reported growing interest in its advanced packaging capabilities. While different from TSMC's CoWoS (chip-on-wafer-on-substrate) technology, Intel's packaging solutions can be made compatible with silicon manufactured by other foundries. According to Intel CFO David Zinsner, advanced packaging is likely to be an early revenue driver for the company's foundry business, with potential announcements of packaging wins expected before the end of the year.

The SK Hynix Indiana plant will not address current memory shortages expected to peak later in 2026, but it represents a significant step toward establishing a more diverse and resilient semiconductor manufacturing ecosystem in the United States. The facility will create high-skilled jobs in the region and support the growing AI and high-performance computing sectors that rely on advanced memory technologies.

As the United States continues to prioritize domestic semiconductor production, investments like SK Hynix's Indiana facility will play a crucial role in reducing dependencies on foreign manufacturing capabilities while supporting the development of next-generation computing technologies.
