Diamond Quanta Launches Adamantine Thermal, Advancing Packaging Roadmap Post-CES 2026
January 19, 2026 | BUSINESS WIREEstimated reading time: 1 minute
Diamond Quanta announced Adamantine Thermal™, an engineered-diamond thermal platform designed for integration into advanced packaging workflows and heterogeneous semiconductor systems. The announcement builds on the company’s CES 2026 Eureka Park debut and reflects growing customer interest in diamond-enabled solutions for next-generation electronics.
The announcement follows Diamond Quanta’s CES 2026 debut, where the company demonstrated 300 mm diamond-on-silicon wafer technology, designed for wafer-to-wafer (W2W) and chip-to-wafer (C2W) bonding compatibility, along with its first commercial diamond glass product, Adamantine Optics™. At CES, the company engaged with system OEMs, semiconductor manufacturers, and ecosystem partners around practical insertion points for diamond within advanced packaging flows.
Extending Diamond Quanta’s CES 2026 Demonstrations
Adamantine Thermal builds directly on the same engineered-diamond manufacturing approach introduced at CES. While diamond is well known for its high intrinsic thermal conductivity, its integration into modern semiconductor packaging has historically been limited by surface roughness, bonding compatibility, and manufacturability at scale.
Diamond Quanta’s approach addresses these challenges by combining:
- CMOS-compatible, low-temperature diamond growth on industry-standard substrates
- Laser-based densification to produce smooth, bond-ready diamond surfaces
- W2W and C2W bonding workflows that support integration into advanced packaging stacks
“Thermal is the most immediate and universal entry point for diamond in electronics,” said Adam Khan, Founder and CEO of Diamond Quanta. “Once diamond can be bonded reliably and at scale, it stops being a research material and becomes a practical platform.”
A key application area for Adamantine Thermal is engineered-diamond glass interposers, where diamond is integrated with glass cores that are already entering advanced packaging workflows. Glass interposers are gaining traction for signal integrity and dimensional stability, and the addition of diamond enables more uniform thermal management while improving flatness and mechanical robustness.
Adamantine Thermal is architected from the outset to support W2W and C2W bonding approaches that are critical for next-generation interposers and stacked systems. By maintaining compatibility with standard fab infrastructure and panel-scale workflows, the platform is designed to bridge today’s passive thermal materials and future diamond-enabled electronic architectures.
Diamond Quanta confirmed that Adamantine Thermal is entering partner evaluation programs, with engineered-diamond interposer concepts advancing in alignment with industry adoption cycles for advanced packaging. The thermal platform complements the company’s recently launched Adamantine Optics offering and reinforces a broader roadmap spanning thermal management, photonics, interposers, and future diamond-enabled systems.
