Technology of EDP is based on the fabrication procedure of large single crystal diamond developed by AIST Japan. The basic technology is lifting off from seed crystal using of ion implantation. The result of this procedure is fabricating planer single crystal, not particle, and 10x10mm mono-crystal and 25x25mm mosaic crystal can be supplied.
- Fabrication technology
- EDP is fabricating single crystal diamond by chemical vapor deposition (CVD)using single crystal diamond as seed crystal. Lift off procedure and jointing 2 or more crystals for making large area are advantage
- EDP supplies high purity diamond crystal which nitrogen concentration is less than 8ppm. Thermal conductivity and hardness are same as Iia diamond. 10x10mm mono-crystal and 20x20mm mosaic crystal, binding few mono-crystals, are commercialized.
