Abstract
Process for manufacturing micromechanical components having a part made of diamond, consisting of at least one tip (3a), in which a substrate (8a) is prepared, in order to form an impression (13a) of the shape desired for the part made of diamond; the part made of diamond is produced by chemical vapor deposition of diamond in the impression and is then separated from the substrate. In order to produce the part made of diamond, a primary film of fine diamond particles, of diameter less than 10 nm, suitable to act as seeds for growth of the diamond are deposited on the substrate, on the surface of the impression (13a), before chemical vapor deposition; the diamond film is then grown by vapor deposition; and the substrate (8a) is then at least partly removed.
