Abstract
A method of fabricating a micromechanical part in a single-piece made of a synthetic carbon-allotrope includes forming a substrate which includes the negative cavity for the micromechanical part to be fabricated, coating the negative cavity of the substrate 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, removing from the substrate a larger thickness than the thickness of the deposited layer, so as to leave a limited thickness of the layer of material in the negative cavity, and 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.
