Patent number: 8562934Abstract: A surface of a substrate comprising microcavities leading out of the substrate is placed in contact with an aqueous solution comprising a plurality of suspended particles and a fabric. Perpendicular pressure is applied the expanse of the substrate between the fabric and the surface of the substrate, and relative movement of the fabric and the surface is applied to the expanse of the substrate. At least one particle is thus fed into each microcavity, therein forming a porous material that is a catalyst material for nanothread or nanotube growth.Type: GrantFiled: March 30, 2009Date of Patent: October 22, 2013Assignees: Commissariat a l'Energie Atomique et aux Energies Alternatives, STMicroelectronics (Crolles 2) SASInventors: Jean-Christophe Coiffic, Maurice Rivoire

Patent number: 8323733Abstract: A surface of a support comprising through micropassages is brought into contact with an aqueous solution comprising a plurality of particles in suspension and a pad. A pressure perpendicular to the plane of the support, between the pad and the surface of the support, and a relative movement of the pad and of the surface in a direction parallel to the plane of the support are applied. At least one particle is thus introduced in each microgap to form a porous material therein.Type: GrantFiled: March 17, 2009Date of Patent: December 4, 2012Assignees: Commisariat a l'Energie Atomique, STMicroelectronics (Crolles 2) SASInventors: Jean-Christophe Coiffic, Maurice Rivoire

Patent number: 8202496Abstract: A molecule is separated from a liquid sample containing said molecule and at least one additional molecule having a larger hydrodynamic diameter than the hydrodynamic diameter of the molecule to be separated, by means of a separation device comprising a substrate, at least one circulation channel arranged in said substrate, and at least one nanotube associated with said molecule to be separated and formed on a free surface of the substrate. Separation is achieved by means of the internal channel of a nanotube, such as a carbon nanotube, presenting an effective diameter chosen in predetermined and controlled manner. The effective diameter of the internal channel is chosen such as to be larger than the hydrodynamic diameter of the molecule to be separated and smaller than the hydrodynamic diameter of the additional molecules of larger hydrodynamic diameters.Type: GrantFiled: February 23, 2009Date of Patent: June 19, 2012Assignee: Commissariat a l'Energie AtomiqueInventors: Jean-Christophe Coiffic, Frédéric-Xavier Gaillard, Pierre Puget

Patent number: 8017025Abstract: A target layer comprising at least one degradable material is deposited on a support. Nanotubes are then formed on the degradable material of the target layer before deposition of an insulating layer is performed. Degradation of the degradable material and elimination of degradation sub-products are then performed by means of the nanotubes passing through the insulating layer thus forming air gaps in the target layer.Type: GrantFiled: May 9, 2008Date of Patent: September 13, 2011Assignee: Commissariat a l'Energie AtomiqueInventors: Frederic-Xavier Gaillard, Jean-Christophe Coiffic

Patent number: 8011091Abstract: A target layer with holes is formed on a bottom conducting layer. Nanotubes are formed in the holes from the bottom conducting layer. A flat insulating layer is then deposited on the target layer, the nanotubes passing through the insulating layer. Air gaps are then formed by selective decomposition of the target layer. The decomposition agent and/or decomposition by-products use the walls and the central holes of the nanotubes to pass between the target layer and the outside. After decomposition, the top conducting layer is formed on the insulating layer. The nanotubes then electrically connect the conducting layers.Type: GrantFiled: July 8, 2008Date of Patent: September 6, 2011Assignee: Commissariat à l'Energie AtomiqueInventors: Frederic-Xavier Gaillard, Jean-Christophe Coiffic

Publication number: 20080317947Abstract: At least one via comprising a bottom and side walls is formed in a layer of insulating material separating two layers of metallic material. A catalyst layer is then deposited. Then an inhibiting layer is formed by directional deposition on the walls of the via and on the insulating material layer, leaving only the part of the catalyst layer that is located in the bottom of the via free. Nanotubes are then formed in said via and electrically connect the two layers of metallic material.Type: ApplicationFiled: June 17, 2008Publication date: December 25, 2008Applicant: COMMISSARIAT A L'ENERGIE ATOMIQUEInventor: Jean-Christophe Coiffic

Publication number: 20080317970Abstract: An electrical connection comprising nanotubes is made between two layers of metallic material separated by a layer of insulating material. After growing the nanotubes, their alignment substantially perpendicularly to the metallic levels is performed by means of an electromagnetic alignment field. Then a sheathing material is deposited, at least partially covering the nanotubes and performing at least individual sheathing of the nanotubes. The electromagnetic alignment field of the nanotubes is maintained during deposition of the sheathing material.Type: ApplicationFiled: June 17, 2008Publication date: December 25, 2008Applicant: COMMISSARIAT A L'ENERGIE ATOMIQUEInventors: Jean-Christophe Coiffic, Jean Dijon
