Element Six, Entegris Team on Diamond Chip Cooling
The collaboration aims to integrate synthetic diamond thermal management into advanced packaging for GPU and RF semiconductor devices.
Updated on Nov. 3, 2026 in Semiconductors

Element Six and Entegris, Inc. announced a strategic collaboration to apply synthetic diamond in semiconductor advanced packaging. The partnership targets diamond-enabled thermal management for GPU and RF devices.
Why it matters
Rising chip power density driven by AI demand is making thermal management a critical factor in semiconductor performance, and conventional cooling technologies are approaching practical limits. Synthetic diamond, which has the highest room-temperature thermal conductivity of any material, is positioned as a candidate to address that gap.
Synthetic diamond is described as having the highest thermal conductivity of any material at room temperature, which underpins its use for heat removal in dense chips. The extraction does not provide measured thermal performance figures or a comparator for the collaboration's approach, and no delivery timeline has been stated.
The players
Element Six
Element Six is a global supplier of engineered synthetic diamond materials, led by CEO Siobhán Duffy.
Entegris, Inc.
Entegris is a materials science and semiconductor materials company whose Chief Innovation Officer and President of Materials Solutions is Olivier Blachier.
The details
The companies will combine Element Six's engineered synthetic diamond materials expertise with Entegris' semiconductor materials science and surface engineering. They will offer semiconductor manufacturers engineered surfaces and bonded diamond technologies for polycrystalline and single-crystal diamond platforms, and are developing wafer-level and heterogeneous integration approaches to reduce manufacturing complexity and thermal boundary resistance.

Semiconductors Thermal Race
The collaboration extends synthetic diamond's established role as a heat-spreading material into commercial advanced packaging for GPU and RF devices. It positions diamond as a candidate for thermal management as AI-driven chip power density pushes conventional cooling toward its limits.
The collaboration is aimed at semiconductor manufacturers rather than end consumers, so its effects would reach users only indirectly through the performance and thermal behavior of future GPU and RF devices. The extraction does not indicate pricing, product availability, or any change in the devices people use today.
The takeaway
Thermal limits are becoming a central constraint on advanced chips as AI workloads grow, making heat-management materials a key area to watch. Readers following semiconductor performance should track whether diamond-based packaging moves from announcement toward commercial adoption.
