The more-than-$4 billion project will package and test Korean-made wafers for U.S. customers. Utility infrastructure and hiring are advancing, but commercial output remains years away.

New utility permits move SK Hynix’s West Lafayette project beyond approval of the main factory shell, allowing work on power and gas infrastructure needed before equipment installation and commissioning. The plant is planned as the company’s first U.S. advanced high-bandwidth memory packaging base; wafer fabrication will remain in South Korea, so the site adds downstream capacity rather than relocating chipmaking. With more than $4 billion committed and up to $458 million in federal subsidies, the project aims to bring packaging and customer collaboration closer to U.S. AI-chip buyers, while mass production remains targeted for the second half of 2029.
Air Liquide plans to invest more than $170 million in two Indiana facilities supplying industrial gases, with operations expected by the end of 2028.
SK Hynix’s next major facility target is completing the cleanroom in October 2028.
The company plans to directly employ approximately 1,000 people once commercial operations begin.
SK Hynix has obtained additional power and gas construction permits for its AI-memory packaging plant in West Lafayette, Indiana, according to industry sources cited by Asia Today in a report translated by UPI. The milestone advances essential infrastructure for the project, which the company says remains on schedule for mass production in the second half of 2029.
The new permits cover power and gas supply facilities, adding essential utility infrastructure to permits for the main factory structure. Semiconductor facilities need reliable electricity and industrial gases before production equipment can be installed, tested and brought into operation.
Gas supply is also taking shape through a dedicated supplier agreement. In July, Air Liquide announced plans to invest more than $170 million in Indiana under a long-term arrangement with SK Hynix. It plans two production facilities supplying ultra-high-purity industrial gases, including nitrogen, oxygen, argon and hydrogen. Those facilities are expected to start operating by the end of 2028.
SK Hynix is recruiting for construction-management and human-resources roles as it builds the workforce needed to operate the plant. The company plans to directly employ approximately 1,000 people once commercial operations begin.
SK Hynix is pursuing the project to strengthen ties with major U.S. customers and respond to growing HBM demand. Local packaging and testing could support closer technical cooperation and improve its ability to respond to those customers.
SK Hynix’s total investment in the Indiana facility exceeds $4 billion. The U.S. Commerce Department has agreed to provide up to $458 million in direct subsidies for the project. That support accompanies a U.S. effort to increase domestic advanced semiconductor packaging capacity and improve the stability of the AI-chip supply chain.
The next major facility target is completion of the cleanroom in October 2028. An SK Hynix official told Asia Today that the project was proceeding as planned.
