Patent ID: 10558169

Abstract:
A method for manufacturing a micromechanical timepiece part starting from a silicon-based substrate, including, forming pores on the surface of at least one part of a surface of said silicon-based substrate of a determined depth, entirely filling the pores with a material chosen from diamond, diamond-like carbon, silicon oxide, silicon nitride, ceramics, polymers and mixtures thereof, in order to form, in the pores, a layer of the material of a thickness at least equal to the depth of the pores. A micromechanical timepiece part including a silicon-based substrate which has, on the surface of at least one part of a surface of the silicon-based substrate, pores of a determined depth, the pores being filled entirely with a layer of a material chosen from diamond, diamond-like carbon, silicon oxide, silicon nitride, ceramics, polymers and mixtures thereof, of a thickness at least equal to the depth of the pores.
