Micron backs Indium Corporation to restart US critical minerals output
Micron Technology has made a strategic investment in Indium Corporation, a Central New York materials manufacturer, to restart domestic processing of critical minerals used in advanced semiconductor fabrication. The deal includes a long-term supply agreement that gives Micron priority access to high-purity indium, gallium, germanium and related compounds refined at Indium Corporation's Rome, New York facility.
The investment sits within Micron's broader $3 billion commitment to strengthen the US semiconductor supply-chain ecosystem, announced in July 2026. Micron did not disclose the specific dollar value of the Indium Corporation investment or the duration of the supply agreement.
The deal
Ben Tessone, Micron's senior vice president and chief procurement officer, said the partnership addresses supply dependencies that reach beyond the company's direct supplier base. "Advanced memory manufacturing depends on a reliable supply of critical minerals. Enabling that requires engagements well beyond our direct suppliers," he said. "Securing these inputs is essential to Micron's long-term growth and technology roadmap."
Indium Corporation chief executive Ross Berntson described the deal as recognition of the company's 90-year manufacturing track record in the region. Micron's New York fab complex in Clay, Onondaga County, is reported to be progressing ahead of schedule as part of what state officials have called the largest private investment in New York State history. The Indium Corporation facility in Rome sits in neighbouring Oneida County, giving Micron a geographically concentrated domestic supply cluster.
The announcement is part of Micron's stated plan to spend more than $250 billion in the United States through 2035, a figure the company ties to rising demand for memory driven by AI workloads and what it terms "Super Intelligence" applications.
Market context
Critical minerals processing has become one of the most politically charged segments of the semiconductor supply chain. China currently dominates global refining capacity for gallium and germanium, and introduced export controls on both materials in 2023, prompting allied governments and chipmakers to accelerate domestic alternatives. The US Bureau of Industry and Security has identified both elements as priority materials under its critical minerals strategy, and the CHIPS and Science Act explicitly links semiconductor incentives to supply-chain resilience.
Micron is not alone in pursuing upstream materials security. Intel and TSMC have both flagged critical minerals sourcing as a long-term risk in recent filings, and a number of specialist refining startups have attracted venture and government funding in the US, Europe and Japan over the past two years. The Indium Corporation deal is notable for involving an established domestic refiner rather than a greenfield project, which should reduce execution risk and time-to-supply compared with building new capacity from scratch.
From a regulatory standpoint, the investment is likely to be viewed favourably by the CHIPS Programme Office as evidence that CHIPS-funded fab construction is catalysing broader domestic supply-chain development, a stated policy objective of the Act. State-level political backing, with endorsements from the Governor of New York and senior US Senate leadership, suggests the project may also attract additional public co-investment or tax incentives, though none have been announced.
Buyers of DRAM and NAND produced at Micron's New York complex will be watching whether the Indium Corporation partnership translates into lower exposure to geopolitically driven material-price spikes, which have periodically disrupted memory production economics over the past decade.
