Abstract:
1. A method of manufacturing a silicon-metal composite micromechanical component, the method including the following steps: a) providing a substrate including a top silicon layer and a bottom silicon layer, between which an intermediate silicon oxide layer extends, b) selectively etching at least one cavity in the top layer to define the pattern of a silicon part of the component; c) continuing the etch of the at least one cavity in the intermediate layer; d) growing a metal layer at least from one portion of the at least one cavity in order to form a metal part in the thickness of the component that insulates the silicon part of the micromechanical component from destructive stress, wherein step d) includes the following additional steps e) releasing the silicon-metal composite micromechanical component from the substrate, wherein the micromechanical component is released by removing the photostructured resin.
