Ultra-Thin Free-Standing Diamond Film for Advanced Semiconductor Packaging and Thermal Solutions

Ultra-Thin Free-Standing Diamond Film is an innovative thermal management material specifically designed for advanced semiconductor packaging, high-power electronics, and emerging photonic systems.

Manufactured using advanced MPCVD diamond growth technology, the film features a self-supporting polycrystalline diamond structure without requiring a silicon carrier substrate. With thicknesses ranging from 5 μm to 25 μm, it combines ultra-high thermal conductivity, electrical insulation, and mechanical flexibility within an exceptionally thin form factor.

Unlike conventional diamond substrates that are thick and rigid, this free-standing diamond film can be integrated directly into advanced packaging architectures, enabling efficient heat extraction from densely integrated semiconductor devices while minimizing package thickness and thermal resistance.

The material is particularly suitable for chiplet packaging, 2.5D/3D integration, wafer-level packaging, AI processors, RF electronics, and next-generation power semiconductor modules.
