Diamond Foundry is a semiconductor manufacturing company based in San Francisco, California, founded in 2013. It produces single-crystal diamond wafers using processes described as converting greenhouse gas into diamond with zero-emission energy, aiming to offer a more sustainable material for advanced electronics. The wafers are intended for use in high-performance systems where thermal management and power efficiency are critical. Its long-range roadmap targets high-power chips in AI and cloud computing, electric-vehicle power electronics, and next-generation wireless technologies. The company has pursued collaborations and expansion efforts, including a partnership with Raytheon Technologies to explore integrating diamond with military-grade GaN transistors, and plans to establish a diamond wafer fabrication facility in Trujillo, Spain, supported by European authorities. Taken together, these moves reflect an effort to scale production and broaden the geographic footprint of its diamond semiconductor materials.
