SK Hynix holds groundbreaking ceremony for $4 billion Indiana AI chip packaging facility

SK Hynix, a South Korean chipmaker, broke ground on Thursday for a $4 billion advanced packaging and research facility in Indiana, marking an expansion of its U.S. operations. The site, situated at the Purdue Research Park in West Lafayette, is slated to commence cleanroom operations in the second half of 2028. Cleanrooms are sterile manufacturing spaces essential for chip production.

The facility will house a forthcoming high-bandwidth memory (HBM) packaging line and an AI semiconductor research and development center. This strategic investment is part of SK Hynix's plan to better serve major U.S. customers such as Nvidia, Microsoft, and Google, while simultaneously bolstering research partnerships with Purdue University and nurturing local engineering talent.

The project's primary goal is to augment advanced packaging capacity in the United States as the burgeoning demand for HBM surges due to AI investments. HBM chips, which stack vertically to accelerate data processing and lower power consumption, have become a pivotal growth catalyst for memory chip manufacturers, particularly after a recent industry downturn.

SK Hynix currently commands 58% of the global HBM market by revenue, outpacing Samsung Electronics and Micron Technology, both of which hold 21% of the market share. The escalating demand for HBM and other advanced memory products is attributed to the rapid proliferation of AI data centers, which have tightened memory supplies and added to the complexity of scaling AI infrastructure.

In 2024, SK Hynix inked a $3.87 billion investment pact with Indiana officials, Purdue University, and U.S. government representatives. The project's total investment has since climbed to over $4 billion, with the company anticipating the facility and associated supply-chain investments to generate approximately 7,000 direct and indirect jobs locally, as well as enhance semiconductor supply-chain resilience.

The U.S. government also lent support, allocating $458 million in grants and up to $500 million in loans under the CHIPS Act in December 2024. SK Hynix's board, meanwhile, approved an investment totaling about 54.3 trillion won ($38.30 billion) through 2031, encompassing 35.2 trillion won for the second phase of construction at its chip fabrication plants in South Korea.
