What Diamond Quanta does
Diamond Quanta is a privately held, Mountain View-based materials company founded in January 2024 that is building what it positions as the first scalable engineered diamond platform for semiconductors, photonics, and protective coatings. Its technology is organized into three modular blocks — Diamond Optical Stacks & Substrates, Defect State Engineering via sub-melt nanosecond Pulsed Laser Annealing (PLA), and Co-Doped Diamond Material Systems — combined with 300mm CMOS-compatible diamond synthesis. These modules underlie two product sub-brands: Adamantine Optics™ (diamond-integrated antireflective coatings for displays, sensors, and harsh-environment optics with hardness exceeding 40 GPa) and Adamantine Thermal™ (thermal interface materials, diamond spreading layers, and diamond-glass interposers with effective conductivity up to 5x copper, supporting wafer-to-wafer and chip-to-wafer bonding for 2.5D/3D advanced packaging). The company also lists core power semiconductor devices (diamond diodes, FETs) and quantum photonic sources using color centers as longer-horizon products.

Diamond Quanta product offering
Product offeringCore offering
Diamond Quanta develops and manufactures engineered diamond material systems, sold under the Adamantine product family. Adamantine Optics™ provides diamond-integrated antireflective coatings for consumer electronics displays, cover glass, and sensor windows. Adamantine Thermal™ provides high-performance diamond thermal solutions (up to 5x copper conductivity) for advanced electronics packaging, including thermal interface materials, diamond-on-glass interposers, and bond-ready diamond surfaces for wafer-to-wafer and chip-to-wafer integration. The company also offers prototyping, product design, and IP licensing of proprietary co-doping and pulsed laser annealing (PLA) defect-engineering methods.
Product overview
Diamond Quanta is building the first scalable engineered diamond platform with two main product sub-brands under the Adamantine™ family: Adamantine Optics™ (ultra-durable diamond optical coatings for displays and sensors) and Adamantine Thermal™ (high-performance diamond thermal solutions for advanced electronics packaging with 5x copper conductivity). The platform is organized around three modular technology blocks: Diamond Optical Stacks & Substrates, Defect State Engineering via Pulsed Laser Annealing, and Defect State Engineering via Co-Doping. These modules combine to enable coatings, substrates, and active devices including diamond-based power semiconductor devices (diodes, FETs) and quantum photonic sources across consumer, automotive, aerospace/defense, and quantum photonics applications. The company also offers prototyping, product design, and IP licensing services.
