Polycrystalline CVD Diamond Wafer — free-standing, polished surface
Polycrystalline CVD Diamond Wafer — free-standing, polished surface
Polycrystalline diamond delivers most of the thermal and electrical benefits of SCD at a fraction of the cost — and can be grown on large-area substrates for wafer-scale applications.
PCD delivers thermal conductivity several times that of copper and silicon. Excellent for high-power thermal management at lower cost than SCD.
PCD grows on large substrates — significantly more area than SCD. Cost-effective for wafer-scale thermal and electrochemical applications.
Boron doping transforms insulating PCD into conductive material. Used as the base for our BDD electrodes on Si/Nb/Ti/glass.
PCD wafers form the substrate for our entire PCD product line — heat spreaders, BDD electrodes, and coated substrates.
GaN-on-PCD, SiC-on-PCD
PCD wafers serve as cost-effective substrates for GaN and SiC power device epitaxy. Larger area than SCD at lower cost.
Sourced for BDD electrodes on Si/Nb/Ti
Heavy-doped PCD wafers are the active layer for our BDD electrodes — electrochemical, water treatment, and sensing applications.
Standard thermal plates
For applications that don't need the absolute peak conductivity of SCD, PCD heat spreaders deliver most of the benefit at lower cost.
