Ground broken on a 4bn dollar memory plant that has been under construction since April
By Staff Writer | 30 August 2026
The ceremony at West Lafayette marks the first American packaging base for high bandwidth memory, on a site of about 133 acres carrying 458m dollars of federal money and up to 712m dollars from the state.
SK hynix held a ceremony to break ground on Thursday 27 August for an advanced packaging fabrication and research facility in the Purdue Research Park at West Lafayette, Indiana. The project is worth more than 4bn dollars. Construction started on the ground in April, so the ceremony marks the moment the project became public rather than the moment work began, which is the usual sequence on schemes of this size and worth saying plainly.
The building is a packaging plant rather than a front end fabrication plant. Wafers will be made in South Korea and China, and some will be sent to Indiana to be stacked and connected into high bandwidth memory, the part of the assembly that has become the constraint on artificial intelligence hardware. The company put its reason for coming plainly.
We will provide our customers with a new source of made-in-U.S. HBM, while strengthening the U.S. semiconductor supply chain and contributing to national and economic security.
Kwak Noh-Jung, chief executive, SK hynix
The programme and the money
The site runs to about 133 acres. The first cleanroom is scheduled to open in October 2028, with mass production of next generation memory starting in the second half of 2029, which puts roughly three years between the ceremony and first output. The company expects about 1,000 direct jobs once production begins, and told reporters that a further 6,000 or so jobs attach to construction and to business partners.
The public money is set out. Up to 458m dollars comes from federal semiconductor funds, and the state incentive package is worth up to 712m dollars, described by the state development body as the second largest in its history. The project was announced in 2024, so the gap between announcement and ceremony ran to a little over two years.
Three years from ceremony to first output, on a plant whose product is already in shortage. The schedule, not the cheque, is the thing to watch.
Why a packaging plant is a construction story
A cleanroom of this class is among the least forgiving structures in commercial building. Vibration limits, air change rates, gas and chemical distribution and the tolerances on the slab all sit outside ordinary industrial practice, and the fit out is usually longer and more expensive than the shell. An October 2028 cleanroom date on a plant that broke ground in April 2026 leaves about thirty months for a building whose services are the product.
Indiana's interest is broader than the plant itself. Purdue has run a semiconductor degree programme since 2022, and the company signed a research and development agreement with the university on the day of the ceremony covering advanced packaging work. Mitch Daniels, the university's interim president, told the ceremony that the day broke ground in far more than the physical sense, and Governor Mike Braun called the scheme the biggest development project in the state's history.
Kwak said the company's total American investments and assets are expected to pass 45bn dollars by 2030. The number to test that against is the October 2028 cleanroom, because on a plant like this the first clean air date is the one every other date hangs from.
