What is a Polycrystalline Diamond Wafer?
A polycrystalline diamond wafer is a synthetic diamond substrate manufactured using chemical vapour deposition (CVD) technology. These diamond wafers are engineered for applications requiring exceptional thermal conductivity, thermal stability, and heat spreading performance.
Compared to conventional materials such as copper, aluminium, AlSiC, and ceramic substrates, polycrystalline diamond wafers offer significantly higher thermal conductivity reaching up to 2200 W/m·K while maintaining low thermal expansion and excellent material stability.
We manufacture CVD polycrystalline diamond wafers for semiconductor packaging, GaN and SiC devices, RF electronics, laser systems, photonics, aerospace, quantum technologies, and advanced thermal management applications.
Custom wafer dimensions, metallisation, polishing, and engineered composite integration are available for OEMs, research institutions, and advanced electronics manufacturers across the UK and Europe.
