摘要:
The invention relates to a method for forming a polymer film on a surface that conducts or semiconducts electricity by means of electrografting. Said method uses an electrolytic solution containing a selected quantity of Brönsted acid. The invention also relates to the electrically conductive or semiconductive surfaces obtained by means of said method.
摘要:
The invention concerns a substrate coated with a transparent organic film and a method for making same, and use thereof. The film-coated substrate is characterized in that the film is an electrically insulating organic polymer and transparent in at least a range of wavelengths, and in that the film is associated with a marker emitting at least in said wavelength range. The invention is in particular applicable in a means for detecting a chemical species, such as a biochip, in a quality control process, a certification process or an authentication process for an object.
摘要:
The invention concerns a mask-free localised grafting of organic molecules capable of being electrically activated, on a composite surface comprising conductive and/or semiconductive portions, by contacting said organic molecules with said composite surface, whereby the grafting is carried out electrochemically in one single step on specific selected zones of said conductive and/or semiconductive portions, said zones being brought to a potential not less than an electric potential threshold determined relative to a reference electrode, said electric potential threshold being the potential beyond which the grafting of said organic molecules occurs.
摘要:
The invention relates to a method of coating a surface of a substrate with a nucleation film made from a metal material, said surface being a conducting or semiconducting surface and comprising recesses and/or protrusions. The inventive method consists in: depositing an organic film on the surface, the thickness of said film being such that the free face thereof conformally follows the recesses and/or protrusions of the conducting or semiconducting surface on which it is deposited; inserting a precursor of the metal material into the organic film deposited on the surface, simultaneously with or following the step consisting in depositing the organic film on said surface; and transforming the precursor of the metal material into the metal material. The inventive method can be used for the production of integrated circuits, microelectronic interconnections and microsystems.
摘要:
The invention relates to a method of depositing or fixing materials to surfaces. More specifically, the invention relates to a method of coating a surface with first and second materials, comprising the following steps consisting in: depositing a first material on the surface; inserting precursor molecules of a second material into the first material deposited on the surface; and transforming the aforementioned precursor molecules of the second material into the second material, such that said second material forms on the surface to be coated and inside the first material deposited thereon. The inventive method can be used to deposit any type of material on any type of surface.
摘要:
The invention relates to a method of soldering a polymer surface with a conducting or semiconducting surface. The inventive method is characterised in that it comprises: a) the electro-grafting of an organic film on the conducting or semiconducting surface and b) an operation consisting in soldering the polymer surface with the thus grafted conducting or semiconducting surface. The invention also relates to the applications of said method and the structures obtained using same.
