Micron Technology is investing in New York-based Indium Corporation to expand domestic critical minerals processing and secure access to materials used in advanced semiconductor manufacturing. Accordingly, Micron’s move marks a new phase in the company’s effort to strengthen U.S. supply-chain capabilities.

The investment will support the expansion of Indium Corporation’s refining and high-purity materials manufacturing operations in Rome, New York, while allowing the restart of domestic processing for critical minerals used in semiconductor production. The companies also plan to establish a long-term supply agreement that will provide Micron with access to those materials.

The initiative is part of Micron’s previously announced plan to invest up to US$3 billion in strengthening the U.S. semiconductor supply-chain ecosystem.

Moving Beyond the Fab

For semiconductor executives, the significance extends beyond a supplier relationship. The agreement reflects a growing industry focus on securing upstream materials required for advanced manufacturing as chipmakers expand domestic production capacity.

“Advanced memory manufacturing depends on a reliable supply of critical minerals. Enabling that requires engagements well beyond our direct suppliers,” said Ben Tessone, senior vice president and chief procurement officer at Micron.

Tessone added that securing such inputs is essential to Micron’s long-term growth and technology roadmap and that expanding U.S. production capacity for critical minerals would help create a more resilient supply chain for semiconductor manufacturing.

The investment is expected to reduce reliance on concentrated global refining capacity, an area that Micron identified as an increasing national security priority.

Building a Regional Semiconductor Ecosystem

The announcement also strengthens connections within New York’s emerging semiconductor manufacturing ecosystem.

Micron said the expanded materials capability will complement its plans to accelerate U.S. fab and technology investments while increasing its expected spending to more than US$250 billion through 2035.

A stronger domestic materials base located in the same state as Micron’s planned New York manufacturing complex is intended to support future memory production as demand continues to rise.

“Micron’s decision to partner with Indium Corporation reflects the trust they’ve placed in our people and our ability to deliver,” said Ross Berntson, president and CEO of Indium Corporation.

Berntson said the companies are working together to expand the supply of semiconductor-grade critical minerals and advance domestic manufacturing capabilities.

Strategic Supply-Chain Signal

The deal underscores how semiconductor manufacturers are increasingly looking beyond wafer fabrication and assembly capacity toward the supporting materials infrastructure required for long-term production growth.

By investing directly in critical minerals processing, Micron is extending its supply-chain strategy into an area that has become increasingly important for manufacturing security, technology leadership, and future capacity expansion.
