Critical Minerals and Materials Accelerator (CMMA)

CMMA Topic Area 2 — Semiconductor Material Refining and Alloying

Supports innovative refining and alloying to improve semiconductor-related material performance.

CMMA Topic Area 2, administered by DOE's Advanced Materials and Manufacturing Technologies Office (AMMTO) under the Office of Critical Minerals and Energy Innovation (CMEI), funds prototyping and piloting of innovative refining and alloying processes for materials critical to domestic semiconductor manufacturing. Issued under FOA DE-TA2-0003589, this track is part of the $69 million Critical Minerals and Materials Accelerator umbrella program. The program targets technologies that are proven at bench scale and ready for pilot or prototype demonstration, specifically addressing the U.S. domestic supply chain gap for semiconductor-grade critical materials. AMMTO administers the program in coordination with DOE's Industrial Technologies Office (ITO).

Eligibility requires American, industry-led partnerships — a U.S. company must serve as prime applicant. Partnerships with national laboratories, universities, and nonprofits are expected and encouraged. A required Letter of Intent had to be submitted by April 24, 2026; teams that did not submit an LOI are not eligible for this FOA. The application deadline is June 25, 2026, making this the second-to-close track within the CMMA program. Individual award amounts are specified in the FOA PDF (DE-TA2-0003589), which was not captured at ingest; the total $69 million pool is shared across all three CMMA topic areas. Program questions should be directed to cmmacceleratornofo@ee.doe.gov.

Applicants with refining or alloying technologies tied to gallium, germanium, indium, silicon carbide, or other semiconductor-critical materials are the primary target for this track. Teams should document bench-scale proof of concept, describe the commercial pathway to domestic production, and articulate the supply chain security benefit to justify investment under the CMEI mission. Industry partners are advised to review the full FOA PDF for cost-share terms, deliverable milestones, and scoring rubric before submitting.
