摘要:
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.

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.
摘要:
The invention relates to a method for creating at least one photovoltaic cell that consecutively includes anisotropically etching a surface (1a) of a crystalline silicon substrate (1) and treating said surface (1a) by means of isotropic etching. Treatment by means of isotropic etching includes at least two consecutive operations that respectively involve forming a silicon oxide thin film (11), having a regulated mean thickness between 10 nm and 500 nm, and removing said thus-formed thin film. The operation that involves forming a silicon oxide thin film (11) on the surface (1a) of the substrate (1) is carried out by means of thermally activated dry oxidation. Such a method makes it possible to improve the surface condition of the surface (1a) of the substrate (1) once the latter is anisotropically etched.
