How CVD forms diamonds. CVD requires a process seed to act as the foundation for chemical deposition. The seed may be a thin slice of diamond or a graphite source, which is placed in a chamber that is evacuated down to a high vacuum (about 20 millitorr) to prevent contamination. Specific gases fill the chamber: generally a carbon-rich gases ...
