Stanford researchers grew a diamond layer directly onto working GaN transistors at ~400°C, achieving a 70°C temperature drop without destroying the chip. Separately, a Japanese company (Okumu Diamond Device) is opening the world's first diamond semiconductor factory in Fukushima in 2025, initially producing components for nuclear decommissioning robots. Diamond conducts heat ~5x better than copper, is electrically insulating, and is radiation-resistant — properties silicon cannot match. The technology also addresses supply chain risks, as diamond can be grown from methane domestically, unlike GaN which depends on Chinese gallium exports. DARPA has integrated Stanford's work into a production program, with results expected in 2027. If commercialized, diamond semiconductors could transform AI data centers, 6G infrastructure, and space electronics. ## Full article daily.dev links to this article rather than hosting it.
