Claim Text:
1. A method of fabricating a micromechanical part in a single-piece made of a synthetic carbon-allotrope, comprising: a) forming a substrate which includes a negative cavity for the micromechanical part to be fabricated; b) coating the substrate, including the negative cavity and a portion of the substrate surrounding the negative cavity, with a layer of the synthetic carbon allotrope in a thickness of between 0.2 μm and 20 μm, the thickness being less than the depth of the negative cavity; c) removing, after step b), from the substrate a larger thickness than the thickness of the layer of the synthetic carbon allotrope deposited by the coating such that the layer of the synthetic carbon allotrope is removed from the portion of the substrate surrounding the negative cavity, so as to leave a limited thickness of the layer of material in the negative cavity; and d) removing the substrate so as to release the single-piece micromechanical part formed in the negative cavity comprising an external surface of comparable roughness to that of the substrate.
