Claim Text:
1. Process for fabrication of a micromechanical and/or nanomechanical structure comprising the following steps, starting from an element comprising a support substrate and a sacrificial layer: a) formation of a first layer on the sacrificial layer, at least part of the first layer being porous; b) formation, on the first layer, an intermediate layer configured to provide the mechanical properties of the structure; c) formation of a second layer on the intermediate layer to provide a stack including the first layer, the intermediate layer and the second layer, at least part of the second layer being porous; d) formation of said micromechanical and/or nanomechanical structure in the stack composed of the first layer, the intermediate layer and the second layer; and e) release of said structure by at least partial removal of the sacrificial layer.
