SK Hynix has commenced construction on a $4 billion advanced packaging and research facility at Purdue Research Park in Indiana, aiming to boost high-bandwidth memory production for AI applications with operations expected to start by the second half of 2028.
- Facility to start cleanroom operations in late 2028
- Focus on high-bandwidth memory packaging and AI R&D
- Project expected to create 7,000 local jobs
What happened
SK Hynix held a groundbreaking ceremony for a new $4 billion facility located at Purdue Research Park in West Lafayette, Indiana. This site is planned to include a cleanroom for advanced packaging of high-bandwidth memory (HBM) chips as well as a research and development center specializing in AI semiconductors. Cleanroom operations are targeted to begin in the latter half of 2028.
The investment represents an expansion of SK Hynix's US footprint in response to growing demand for memory chips tailored for AI workloads. This facility aims to strengthen production capacity and foster innovation by positioning itself close to prominent American customers such as Nvidia, Microsoft, and Google, while also building local engineering talent and partnerships with Purdue University.
Why it matters
HBM is a critical component for AI processors because it allows for high-speed data transfer and energy-efficient performance, fulfilling the immense computing requirements of modern AI applications. SK Hynix currently holds a dominant 58% share of the global HBM market, outpacing competitors Samsung and Micron. The planned facility is expected to address supply constraints and capacity gaps driven by surging AI data center investments.
This project also aligns with broader US efforts to bolster semiconductor supply chain resilience through incentives like the CHIPS Act, which has provided over $950 million in grants and loans to support the endeavor. The facility is projected to generate approximately 7,000 direct and indirect jobs locally, contributing significantly to the regional economy and US semiconductor independence.
What to watch next
Key milestones to follow include the start of cleanroom operations in mid-2028 and progress updates regarding the integration of AI research with memory production at the Indiana site. Observers should also monitor how SK Hynix’s expanded US presence influences partnerships with major AI chip consumers like Nvidia and Microsoft, as demand for next-generation memory intensifies.
Additionally, the broader investment plans approved by SK Hynix’s board through 2031, including multi-trillion won spending on domestic facilities in South Korea, will be important to track as part of their global strategy. Regulatory and financial support from the US government will remain critical to the project's timely execution and competitive positioning.
