The method of fabricating a multi-level, metallic microstructure includes the steps consisting in structuring a first layer of photosensitive resin so as to obtain a first level of a resin mould, the aperture in the first resin layer revealing a conductive surface of a substrate, structuring a second photosensitive resin layer over the first level of a resin mould so as to obtain a multi-level resin mould, the apertures in the multi-level mould revealing the conductive surface of the substrate, galvanically depositing a metal or alloy in the apertures of the multi-level resin mould and separating a multi-level metallic structure formed by the metal or alloy deposited in the apertures from the substrate and the multi-level resin mould.

Method of fabricating multi-level metallic parts by the liga-UV technique

The invention concerns a method of fabricating a metallic microstructure, characterized in that it includes the steps consisting in forming a photosensitive resin mold by a LIGA-UV type process, and in the uniform, galvanic deposition of a layer of a first metal and then a layer of a second metal form a block, which approximately reaches the top surface of the photosensitive resin.

Method of fabricating a metallic microstructure and microstructure obtained via the method

The invention relates to a method () of manufacturing a silicon-metal composite micromechanical component () combining DRIE and LIGA processes. The invention also relates to a micromechanical component () including a layer wherein one part () is made of silicon and another part () of metal so as to form a composite micromechanical component (). The invention concerns the field of timepiece movements.
