Abstract:
1. A process for manufacturing a mask having submillimetric openings, the mask produced on a main face of a substrate by deposition of a liquid masking layer as a solution and drying, the process comprising: depositing a first solution of colloidal nanoparticles stabilized and dispersed in a first solvent to form a first masking layer, the nanoparticles having a glass transition temperature T drying the first masking layer at a temperature below said temperature T wherein the process comprises forming a solid mask zone via a liquid deposition, on the face, of a second masking layer, the solid mask zone being adjacent to and in contact with the network mask zone, and/or the process comprises forming at least one cover zone via the placement of at least one cover on the face, the cover zone being in contact with the network mask zone, and/or after the drying of the first masking layer, the process comprises forming a filled mask zone via the liquid filling of the openings of a portion of the network mask zone, wherein the solid mask zone, the cover zone and the filled mask zone each define an electrically insulating zone in which a deposition of an electroconductive material is prevented in said electrically insulating zone, said deposition of the electroconductive material to fill said submillimetric openings in the network mask zone.
