CVD Diamonds In order to create a CVD diamond, a process seed is needed. This seed may be a diamond or graphite slice. A vacuum chamber is used to place the seed. The chamber is vacuumed to a 20-millitorr level. The chamber is then filled with a carbon-rich gas, hydrogen, and oxygen. Energy is required …
