“Why Diamond?”

Diamond is a unique material in many ways beyond just its position on the Mohs scale. It possesses the highest thermal conductivity of any material, low thermal expansion, and possesses incredible electrical resistivity. These characteristics make it suitable for applications where precision is a necessity or conditions are extreme. As costs of CVD diamond comes down, diamond is finding greater use in science and industry.

Specifically:

Highest thermal conductivity   of any material, up to 2000 W/mK

Low absorption coefficient allows higher power outputs to be transmitted through the window without suffering damage or distortion.

Widest transmission spectrum from visible to far IR — from 220 nm to >50 µm—x-ray, infrared, terahertz and microwave

Hardest material known to science

Highly chemically inert

Wide band-gap semiconductor material

Electric insulator with high breakdown field strength

CSMH is an advanced semiconductor manufacturing technology based joint venture company that produces high quality Diamond wafer and AlN template on various substrate including Si, sapphire, and polished diamond. We have strong R&D team and actively collaborate with best research group around the world.

Currently, we are providing the thermal grade polycrystalline diamond as an effective diamond heat sink to solve the heat issue in temperature sensitive device, such as power devices, lasers and avalanche photodiodes etc.
