About
Diamond Foundry is pioneering the 'Diamond Age' of semiconductor technology by manufacturing single-crystal diamond wafers at scale — the world's first. Diamond outperforms every known semiconductor material in thermal conductivity, breakdown voltage, and electron mobility, making it ideal for the most demanding applications in modern tech infrastructure. The company's full-stack technology includes diamond wafer production, diamond transistors, and complete electronics integration. Their solutions are targeted at three major verticals: AI chip thermal management (enabling up to 10x faster performance with less energy), AI data centers (delivering 5x more power per 1U rack), and electric vehicle power electronics (enabling 8x more power output). Diamond Foundry operates its fabrication facilities with a 'real zero' carbon footprint, making it one of the most sustainable advanced semiconductor manufacturers in the world. Their Spain fab expansion, announced in 2025, adds $2.77B in manufacturing capacity to meet growing global demand. The company is backed by major investors and has been featured in outlets including the Wall Street Journal as a key enabler of faster, more efficient microchips. Diamond Foundry is suited for enterprise technology companies, AI hardware developers, automotive OEMs, and data center operators looking for breakthrough performance at the semiconductor level.
