CVD Diamond

Description

• Our integrated CVD diamond substrate series covers all mainstream industrial grades, including electronic-grade single crystal diamond blanks with customizable (100)/(110)/(111) crystal orientation like the 3×3×1.5mm and 5×5×1.5mm polished substrates displayed, thermal-conductive polycrystalline heat spreaders, high-transmittance optical windows, NV quantum sensing single crystal wafers, boron-doped conductive BDD electrode plates and wear-resistant CVD tool blanks.

  All CVD materials are manufactured by advanced vapor deposition equipment in our Taiwan production base, with optional double-sided ultra-polishing, ultra-flat finishing, titanium/gold/platinum metallization, laser cutting, drilling and hetero-bonding with Si, Cu, Mo and SiC substrates. The full lineup features ultra-high thermal conductivity up to 2200 W/mK, wide-spectrum optical transmittance, ultra-low internal defects, excellent chemical inertness and adjustable boron doping concentration for conductive electrode use.

  These CVD diamond substrates are widely applied in GaN radio frequency chips, SiC power modules, high-power laser optical systems, quantum magnetic sensing, industrial electrochemical wastewater treatment and precision non-ferrous metal cutting. We support fully customized size, thickness, crystal orientation and surface processing, with both small lab sample pieces and large-volume industrial bulk supply available for global semiconductor, aerospace, photonics and new energy customers.
