CVD diamond (Chemical Vapor Deposition-Diamond)
Heatspreaders for Semiconductor laser submount, Power transistor substrate
CVD diamond is polycrystalline diamond without binder, obtained by the Chemical Vapor Deposition method (CVD). It allows the forming of various metallized thin films for chip mount and wire bonding.
