SK Hynix breaks ground on $4B advanced packaging facility in Indiana

SK Hynix held a groundbreaking ceremony on August 27 for its first US advanced packaging facility, located at Purdue University’s Research Park in West Lafayette, Indiana.

The investment exceeds $4 billion. The facility spans 133.5 acres. And the ambition behind it is simple: make high-bandwidth memory (HBM) chips on American soil to feed the AI industry’s insatiable appetite for faster, denser memory.

What SK Hynix is actually building

This isn’t a traditional chip fabrication plant. It’s an advanced packaging facility, which means silicon wafers will still be manufactured at SK Hynix’s fabs in South Korea, then shipped to Indiana for the intricate process of stacking and packaging them into finished HBM products. The end result qualifies as “Made in USA,” which matters quite a bit given the current geopolitical climate around semiconductor supply chains.

SK Hynix is targeting October 2028 for cleanroom operations to begin. Mass production of HBM4E, the company’s next-generation high-bandwidth memory product, is expected to start in the second half of 2029.

HBM is the memory technology that sits inside the AI accelerators powering data centers for companies like Nvidia, Microsoft, and Google.

Jobs, politics, and the AI supply chain

The groundbreaking drew Indiana Governor Mike Braun and US Senator Todd Young. SK Hynix expects the facility to create approximately 1,000 direct jobs at the site. The broader supply chain impact is estimated at around 7,000 jobs.

SK Hynix is establishing a dedicated Advanced Packaging R&D Testbed in collaboration with Purdue University, creating a pipeline between academic semiconductor research and commercial production.

Why this matters for the AI hardware race

The US CHIPS Act has been the primary catalyst for domestic investment, and projects like SK Hynix’s Indiana facility are exactly the kind of outcomes that legislation was designed to produce.

The Indiana plant complements ongoing expansion at SK Hynix’s facilities in South Korea, including an advanced packaging fab in Cheongju, where the company fabricates the advanced memory products that go into AI accelerators. Having packaging capabilities in the US reduces shipping times to American customers and provides a hedge against potential trade disruptions between Asia and the West.

SK Hynix has been the dominant HBM supplier, providing HBM chips to Nvidia for its market-leading GPU platforms. The Indiana facility marks SK Hynix’s first dedicated HBM packaging site outside its home country.
