CEO Interview with Eric Tsai of Mivium

What happened

Mivium, Inc., a US-based materials technology company in Fremont, California co-founded in 2022 by Eric Tsai (CEO), stated in an interview that it produces submicron gallium nitride (GaN) powder and has just published independently characterized results. The announced material is phase-pure hexagonal wurtzite GaN in a 300 to 500 nanometer range with uniform distribution and faceted morphology, confirmed by independent third-party characterization using SEM, EDS, XRD, XPS, GDMS and ICP-MS. The company is US-based and has raised more than $10.5 million. Target applications are crystal growth, substrate development and thin-film work; the company states it is not a wafer or device company and does not assume its powder drops into every epitaxy flow, with fit being application-specific. The same platform extends to other wide bandgap materials, including gallium oxide and boron nitride. On thin films, Mivium has completed initial in-house GaN deposition work derived from the powder platform, but describes it as early-stage R&D. The interview cites demand from AI power, EVs and RF pulling on upstream supply, and customer concerns about batch-to-batch repeatability and supply; these are company statements. The source does not report any price change, capacity change or supply-demand event.
