  • Publication number: 20100029031
    Abstract: The invention relates to a method of fabricating and electromechanical device on at least one substrate, the device including at least one active element and wherein the method comprises: a) making a heterogeneous substrate comprising a first portion, an interface layer, and a second portion, the first portion including one or more buried zones sandwiched between first and second regions formed in a first monocrystalline material, the first region extending to the surface of the first portion, and the second region extending to the interface layer, at least one said buried zone being made at least in part out of a second monocrystalline material so as to make it selectively attackable relative to the first and second regions; b) making openings from the surface of the first portion and through the first region, which openings open out to at least one said buried zone; and c) etching at least part of at least one buried zone to form at least one cavity so as to define at least one active element that is at

  • Publication number: 20090325335
    Abstract: The invention relates to a method of making a component from a heterogeneous substrate comprising first and second portions in at least one monocrystalline material, and a sacrificial layer constituted by at least one stack of at least one layer of monocrystalline Si situated between two layers of monocrystalline SiGe, the stack being disposed between said first and second portions of monocrystalline material, wherein the method consists in etching said stack by making: e) at least one opening in the first and/or second portion and the first and/or second layer of SiGe so as to reach the layer of Si; and f) eliminating all or part of the layer of Si.

  • Publication number: 20090321887
    Abstract: The invention relates to a method of fabricating an electromechanical structure presenting a first substrate (1) including at least one layer (1?) of monocrystalline material covered in a sacrificial layer (2) that presents a free surface, the structure presenting at least one mechanical reinforcing pillar received in said sacrificial layer, the method being characterized in that it comprises: a) making at least one well region (51, 52) in the sacrificial layer (2) by etching, at least in the entire thickness of the sacrificial layer (2), the well region defining at least one said mechanical pillar; b) depositing a first functionalization layer (4, 31) of a first material, relative to which the sacrificial layer is suitable for being etched selectively, the functionalization layer (4) filling at least one well region (51) at least partially and covering the free surface of the sacrificial layer (2) at least around the well region(s); and b?) depositing a filler layer (6, 32) of a second material different

  • Publication number: 20090317931
    Abstract: The invention relates to a method of fabricating an electromechanical device including an active element, wherein the method comprises the following steps: a) making a monocrystalline first stop layer on a monocrystalline layer of a first substrate; b) growing a monocrystalline mechanical layer epitaxially on said first stop layer out of at least one material that is different from that of the stop layer; c) making a sacrificial layer on said active layer out of a material that is suitable for being etched selectively relative to said mechanical layer; d) making a bonding layer on the sacrificial layer; e) bonding a second substrate on the bonding layer; and f) eliminating the first substrate and the stop layer to reveal the surface of the mechanical layer opposite from the sacrificial layer, the active element being made by at least a portion of the mechanical layer.

  • Patent number: 7247226
    Abstract: The present invention concerns a lining support comprising a plurality of conductive pads (12) associated with a shared addressing contact (18) and means of selecting at least one pad to be lined by electrochemical means among the plurality of pads. In accordance with the invention, the selection means comprise means (20) of shifting a polarisation voltage, connected between the shared addressing contact and at least one pad to be addressed. Application to the lining of conductive pads.

  • Patent number: 7196385
    Abstract: An electromechanical microstructure including a first mechanical part formed in a first electrically conductive material, and which includes a zone deformable in an elastic manner having a thickness value and an exposed surface, and a first organic film having a thickness, present on all of the exposed surface of the deformable zone. The thickness of the first film is such that the elastic response of the deformable zone equipped with the first film does not change by more than 5% compared to the response of the bare deformable zone, or the thickness of the first film is less than ten times the thickness of the deformable zone.

  • Publication number: 20040037736
    Abstract: A method of sterilizing at least one article by means of a plasma and in the presence of humidity using a non-biocidal gas containing oxygen and nitrogen, the article being placed outside the discharge in a sealed treatment enclosure that is subjected substantially to atmospheric pressure, the method comprising the following steps: introducing the humidified non-biocidal gas into the treatment enclosure; creating a first plasma discharge A for a determined duration enabling the effectiveness of the sterilizing species created during the following stage to be guaranteed within the entire enclosure; creating a second plasma discharge B during a determined duration enabling said article to be sterilized; and rinsing the treatment enclosure during a determined duration so as to guarantee that it contains a non-polluting atmosphere when the enclosure is subsequently opened.
