A method for locating, in a deposition line including a succession of compartments, an origin of a defect affecting a stack of thin layers deposited on a substrate in the compartments, in which each thin layer is deposited in one or more successive compartments of the deposition line and pieces of debris remaining on the surface of a thin layer deposited in a compartment act as masks for the subsequent depositions of thin layers and are the origin of defects, includes obtaining at least one image showing the defect, determining, from the at least one image, a signature of the defect, the signature containing at least one characteristic representative of the defect, and identifying at least one compartment of the deposition line liable to be the origin of the defect from the signature of the defect and using reference signatures associated with the compartments of the deposition line.

The invention relates to a heating element comprising a substrate () equipped with a thin-film multilayer, the thin-film multilayer comprising a film () suited to being heated, this film having a sheet resistance of between 20 and 200 &#x3a9;/square, the heating element also comprising two conductive collectors suited to being fed with electrical voltage, the film suited to being heated being a transparent electrically conductive oxide film and the film () suited to being heated not being machined and being electrically connected to the two conductive collectors, the film () suited to being heated having a thickness of between 50 nm and 300 nm. The invention allows a heating element, with a film suited to being heated that is simple to manufacture, to be easily installed in an electric vehicle or easily connected to the national grid.

Film-type heating element

A process for manufacturing a mask having submillimetric openings, in which: for a masking layer, a solution of colloidal nanoparticles that are stabilized and dispersed in a first solvent is deposited, the particles having a given glass transition temperature T, the drying of the masking layer is carried out at a temperature below the temperature Tuntil a mask having a two-dimensional network of submillimetric openings is obtained with substantially straight mask area edges, in a zone referred to as a network mask zone, a zone free of masking is formed on the face by mechanical and/or optical removal of at least one peripheral portion of the network mask zone. The invention also relates to the network mask and the grid with an electroconductive solid zone that are thus obtained.

A method of manufacturing a submillimetric electroconductive grid coated with an overgrid on a substrate includes: the production of a mask having submillimetric openings by the deposition of a solution of colloidal polymeric nanoparticles that are stabilized and dispersed in a solvent, the polymeric particles having a glass transition temperature Tand the drying of the masking layer at a temperature below the Tuntil the mask, with straight edges, is obtained, the formation of the electroconductive grid by a deposition of electroconductive material, referred to as grid material, a heat treatment of the masking layer with the grid material at a temperature greater than or equal to 0.8 times T, thus creating a space between the edges of mask zones and the lateral edges of the grid; a deposition of a layer, referred to as an overlayer, made of a material referred to as overlayer material, on the grid and in the space between the edges of mask zones and the lateral edges of the grid; a removal of the masking layer. The invention also relates to the grid thus obtained.

Method for manufacturing a submillimetric electrically conductive grid coated with an overgrid

A process for manufacturing a mask having submillimetric openings, in which: for a masking layer, a first solution of colloidal nanoparticles in a first solvent is deposited, the particles having a given glass transition temperature T, the drying of the masking layer, known as the first masking layer, is carried out at a temperature below said temperature Tuntil a mask having a two-dimensional network of substantially straight-edged submillimetric openings, that defines a mask zone known as a network mask zone is obtained, a solid mask zone is formed by a liquid deposition, on the face, of a second masking zone, the solid mask zone being adjacent to and in contact with the network mask zone, and/or at least one cover zone is formed, the cover zone being in contact with the network mask zone, and/or after the drying of the first masking layer, a filled mask zone is formed by filling, via a liquid route, openings of a portion of the network mask zone. The invention also relates to the mask and the electroconductive grid obtained.
