Abstract
A radiofrequency wave apparatus and method which provides a relatively high concentration of reactive species from a plasma for the treatment of a surface particularly of a substrate (31) with a complex geometry in a holder (62) which masks a portion of the substrate. The radiofrequency waves are preferably microwaves or UHF waves. The apparatus and method is particularly useful for rapid plasma assisted chemical vapor deposition of diamond on a portion of the substrate, particularly on surfaces of objects with complex geometries such as a drill (60) or a seal ring (64).
