Company Overview
About Diamond Foundry
Diamond Foundry is a Silicon Valley company pioneering the industrial production of single-crystal diamond wafers for next-generation semiconductor applications. The company operates plasma reactor technology to grow diamond crystals from scratch — the same carbon-lattice structure as natural diamonds — at the scale needed for commercial semiconductor manufacturing. In November 2023, Diamond Foundry produced the world''s first 100mm single-crystal diamond wafer, a critical milestone toward volume production. Diamond is the ultimate semiconductor material: it offers thermal conductivity 5x better than copper, breakdown voltage 10x better than silicon carbide, and a figure of merit 17,200x superior to silicon for power electronics.
Business Model & Competitive Advantage
Diamond Foundry''s wafers target three high-value applications: AI compute, where diamond thermal management dramatically improves GPU and accelerator performance; electric vehicles, where diamond-based power electronics are 6x smaller than silicon equivalents at higher efficiency; and 5G/wireless infrastructure, where diamond enables higher-frequency, higher-power RF components. The company committed approximately EUR 2.35 billion to build a solar-powered diamond wafer manufacturing facility in Trujillo, Spain in late 2025, supported by the European Investment Bank — establishing Europe''s largest high-tech diamond semiconductor hub. The facility will serve European and global demand for power electronics and telecom components.
Competitive Landscape 2025–2026
Diamond Foundry operates with a zero-carbon manufacturing footprint, using renewable energy for its plasma reactors. The company also sells lab-grown diamonds for jewelry under consumer-facing brands. Its semiconductor division is positioned as a long-cycle deep-tech bet: diamond wafers require sustained R&D investment and manufacturing scale before they can challenge incumbent silicon and SiC at volume, but early customers in AI and EV power electronics are actively evaluating diamond as the next step-change material for thermal management and power efficiency.
