About Mivium
Mivium develops wide bandgap semiconductor materials. Its first product is submicron gallium nitride (GaN) powder. Independent third-party testing found phase-pure hexagonal wurtzite GaN with particles of 300 to 500 nanometers. Qualified crystal-growth, epitaxy, and materials teams can request evaluation samples. Mivium plans to follow the powder with GaN substrates.
Mivium was founded in 2022 and is based in Fremont, California. Eric Tsai is co-founder and chief executive officer. Chandra Deshpandey is chief technology officer and an emeritus professor of materials science and engineering at UCLA. Rick Qiu is co-founder and general manager of powder. Jim Qiu is co-founder and chairman of the board. Ginetto Addiego is chief operating officer. Total capital raised is more than $10.5 million.

Why Investors Backed Mivium
Mivium, Inc. makes submicron gallium nitride (GaN) powder for semiconductor materials teams. Independent testing found the powder phase-pure, with particles of 300 to 500 nanometers. The company has raised more than $10.5 million in total, including a $4.23 million private placement closed in July 2026. Powder comes first, and GaN substrates are the stated next step.
The problem it targets
Mivium's case is that GaN production has been held back by scarce high-quality substrates and tight supply chains, which raise costs and make production harder. It also argues that the usual manufacturing processes for silicon and gallium arsenide are highly toxic and polluting.
What the product does
The product is submicron GaN powder made with a patented process. Mivium's position is that the process delivers high-purity GaN at scale without the toxic byproducts of conventional methods. Characterization used SEM, EDS, XRD, XPS, GDMS, and ICP-MS. Mivium is also developing GaN thin films from the powder, with initial deposition done in-house. The platform extends to gallium oxide and boron nitride.
Progress so far
The first goal, as of May 2025, was to get the GaN particle prototype to market. On October 6, 2026, Mivium announced that it had produced high-purity submicron GaN particles. Chandra Deshpandey, the chief technology officer, argues that no one had shown submicron GaN at this quality and scale before. Mivium planned to show samples and data at SEMICON West, booth 5582, in San Francisco on October 13 to 15, 2026.
Who backs it
A $5 million equity round closed through the Equifund Crowd Funding Portal and was announced on May 1, 2025. It brought total funding to more than $6.34 million. In July 2026, Mivium closed a $4.23 million private placement. Total capital raised now exceeds $10.5 million. The money goes to R&D, materials characterization, thin-film development, and talks with potential commercial and strategic partners.
How the market is moving
Mivium's view is that silicon is reaching its performance limits and GaN is the next generation technology. It names AI data centers, electric vehicles, and aerospace and defense as uses that need GaN's speed and energy efficiency. It also expects 5G and 6G, EV infrastructure, AI, and space exploration to exhaust silicon and gallium arsenide devices. The company adds that GaN has ten times the electrical breakdown strength of silicon and three times the bandgap.
