摘要:
The invention concerns a device consisting of microstructures or nanostructures on a support. The invention is characterised in that the support comprises: a substrate (1) including at least a part made of crystalline material, said part having a surface (2) exhibiting a stress field or a topology associated with a stress field, the stress field being associated with dislocations; an intermediate layer (3) integral with said surface (2) and having a thickness and/or a composition and/or a state enabling transmission of said stress field through said layer up to its free surface which bears the microstructures or nanostructures (4).

The invention generally pertains to the field of solid immersion lenses for optical applications in high resolution microscopy. The lens of the invention includes a spherical sector (1) limited by a planar surface (11) and an object (2) having nanometric dimensions arranged on the planar surface at the focus of said solid immersion lens. A light-opaque layer (3) having a central opening (31) with nanometric dimensions can be provided on the planar surface, said opening being centred on the focus of the solid immersion lens. The nano-object can be a tube or a thread having a cylindrical shape. The lens of the invention can be made using lithography techniques.
摘要:
The invention relates to a method for assembling, by molecular adhesion, a first substrate and a second substrate along the contact faces, the contact face of the first substrate having an electrically conductive layer on at least a portion of its surface. The inventive method comprises the following steps: depositing a connecting layer on at least a portion of the electrically conductive layer, said connecting layer being capable of ensuring a molecular adhesion with an area of the contact face of the second substrate and capable of being combined with the electrically conductive layer in order to form a conductive alloy; placing the connecting layer of the first substrate in contact with the area of the contact face of the second substrate and bonding it by molecular adhesion; transforming, on all or a portion of its width, all or part of the electrically conductive layer with all or part of the connecting layer and with at least a portion of the width of the area of the contact face over all or part of the surface of the second substrate in order to form a conductive alloy area.

The invention relates to an assembling method for enabling localized electrical connections between areas situated on a face of a first substrate and corresponding areas situated on a face of a second substrate, said faces facing one another and at least one of the substrates having a surface topography. The method is characterized by the following steps consisting of: forming an intermediate layer comprising at least one burying layer on the face of the substrate or of the substrates having a surface topography in order to make it/them topographically compatible with the molecular bonding of these faces of the substrates to one another, the resistivity and/or thickness of the intermediate layer being chosen for enabling said localized electrical connections; placing the two faces in contact, the substrates being positioned in a manner that enables them to ensure the electrical connections between the areas situated on the first substrate and the corresponding areas situated on the second substrate, and; bonding the faces of the first and second substrate by molecular adhesion.
