Thermal Grade Diamand Wafers and Slices

Diamond exhibits the highest thermal conductivity among all materials. Its thermal

conductivity is up to 2000 W/mK which is higher a lot than that of copper. Therefore

diamond wafers and slices become more and more popular in thermal management as

heatspreaders,heatsinks, lithographically patterned metallization, electrical isolation

between top and bottom metallization, stress relieving slits for stress free mounting etc.

CVD diamond heat spreaders in various shapes,and the typical parameters are as

follows:

Material                                    thermal conductivity >1000 W/mK

Diameter                                 Up to 70mm

Surface                                     Polished, lapping, as-cut

Thickness                               100 - 1500 µm

Young's modulus                  1000-1100Gpa

Density                                    3.5g/cm3

Optical                                     grade diamond wafers

Optical grade diamond wafers are used as window for infrared beam splitters, lenses for

terahertz spectroscopy and CO2 laser surgery,Brewster Windows for multi-spectral

applications such as free electron lasers, multi-wavelength IR lasers or terahertz optical

systems,for Units attenuated total reflection) spectroscopy,for diamond Liquid Cells.

Large Sized Diamond Substrate

Long known as one of the top industrial jewel parts suppliers, we have been continuing to improve its jewel substrate manufacture technology when it mass produced 14mm*14mm single crystal diamond substrates for post-Si semiconductors that build optical parts, heat spreader, audio parts and quantum computer. At present,  we are able to manufacture substrates in the size of around 1 inch square with the exclusive, patented microneedle growth technology enabling stable production of crack-free large diamond substrate. Carrying on with the technology, we promised to scale up the size of its substrate products to up to 50mm*50mm (2 inch square).
