Abstract: A method for bonding two free surfaces, respectively of first and second different substrates, includes a formation step, on the free surface of the first substrate, of a self-assembled mono-molecular layer consisting of a thiol compound of the SH-R-X type, where -R is a carbonaceous chain and -X is a group selected from the group consisting in -H, -OH and -COOH, at least said free surface of the first substrate being formed by a material able to form molecular bonds with the -SH group of the thiol compound. The method also includes preparing the free surface of the second substrate consisting in saturating the free surface of the second substrate with -H groups if -X is a -H group or with -OH groups if -X is selected from the group consisting in -OH and -COOH, and placing the two free surfaces in contact.

Abstract: The invention concerns a method for transferring at least one object of micrometric or millimetric size onto a host substrate by means of a handle. The method comprises the following steps: fixing a polymer handle on said object in order to be able to obtain a structure, constituted of the handle and the object superimposed, and deformable, surface preparation of the face of the object opposite the handle with a view to its adhesion on a face of the host substrate, bringing into contact and adhesion of said face of the object on said face of the host substrate after deformation of at least the handle, removal of the polymer handle.

Abstract: The device is implemented in epitaxial semiconductor material in the form of a piled-up structure comprising a layer of semiconductor material (13) transferred to the first face of a support substrate (11) and joined to it by the intermediary of an insulator layer (12), and epitaxial layers (14,15) supported by the semiconductor layer. The electric connection contacts (16,17) of the device are provided on the upper epitaxial layer and on the second face of the support substrate. The electric link metallizations (19) are extended from electric contacts (18) on the lower epitaxial layer to the support substrate through the insulator layer thus linking the epitaxial layer to the other contact (17) through the support substrate which is sufficiently conducting. The support substrate (11) is made of an electrically conducting material, or of a semiconductor material from the group comprising SiC, GaN, AlN, Si, GaAs, ZnO and Ge. The support substrate is overdoped on the side of the interface with the insulator layer. The epitaxial material comprises layers (14,15) of different doping level. The epitaxial material is from the group comprising SiC, GaN, AlGaN, InGaN, and diamond. The electric connection contacts comprise at least one Schottky contact. The insulator layer is of a material from the group comprising silicon dioxide (SiO2), silicon nitride (Si3N4), and diamond. The semiconductor layer (13) is of a material from the group comprising SiC, GaN, AlN, Si, ZaO, and diamond. A semiconductor circuit (claimed) is associated with at least one semiconductor power device (claimed), and with at least one semiconductor device which is not linked to the second face of the support substrate.

Abstract: The molecular adhesion of a second electronic composite on to a first electronic composite (1), the contact surface of the first containing a polymer (4), comprises the coating by a linking layer (5) of at least a part of the polymer surface. The molecular adhesion takes place between the linking layer and the second electronic composite. An independent claim is also included for a three-dimensional matrix of electronic composites produced by this method of molecular adhesion.

Abstract: Un procédé de collage entre une première surface (1) munie d'au moins une zone en cuivre (3) entourée d'une zone en oxyde de silicium (4) et une seconde surface (1') comprend une opération de traitement de la première surface (1) par plasma, avant la mise en contact de la première surface (1) avec la seconde surface (1'). Le plasma est formé à partir d'une source gazeuse contenant un agent de nitruration de l'oxyde de silicium et un agent réducteur de l'oxyde de cuivre à base d'hydrogène. La source gazeuse peut comporter un mélange gazeux N et NH et/ou H ou bien un mélange gazeux N O et H ou bien encore de l'ammoniac qui joue alors à la fois le rôle d'agent de nitruration et celui d'agent réducteur. Le plasma obtenu à partir de cette source gazeuse comprend alors nécessairement de l'azote et de l'hydrogène, ce qui permet, en une seule opération, d'assurer un collage performant entre les première et seconde surfaces (1, 1').
