ABSTRACT:
A cyclotron resonance chemical vapor deposition method of making a diamond or diamond-like material on a substrate characterized by the use of a higher pressure range of 0.1 to 300 torr, where the substrate is approximately positioned where a standing wave of the applied microwave established in a reaction chamber attains a maximum value.
