Abstract: A method for manufacturing a structure having a textured surface, including a substrate made of mineral glass having a given texture, for an organic-light-emitting-diode device, the method including supplying a rough substrate, having a roughness defined by a roughness parameter Ra ranging from 1 to 5 ?m over an analysis length of 15 mm and with a Gaussian filter having a cut-off frequency of 0.8 mm; and depositing a liquid-phase silica smoothing film on the substrate, the film being configured to smooth the roughness sufficiently and to form the textured surface of the structure.

Abstract: The invention relates to a method of fabricating “open” microfluidic devices by screen printing. The method comprises steps consisting in: a) depositing a mixture of a glass, glass-ceramic or ceramic precursor material and of an organic medium onto said substrate, which is made of a material chosen from glass, glass-ceramic and ceramic, by screen printing in order to form at least one screen-printed feature in a desired pattern, each feature corresponding to a microfluidic device; and b) firing the screen-printed feature(s) at a temperature allowing the precursor material to bond to the substrate by melting. The subject of the invention is also a method of fabricating microfluidic devices that are “closed” by a sheet of glass, glass-ceramic or ceramic.
