Estimating the term…
The present invention relates to the fields of physics, material sciences and micro and nano electronics, and concerns a method for producing a rolled-up electrical or electronic component, as can be used for example as a capacitor, or in aerials. The object of the present invention is to provide a low-cost, environmentally friendly and time-saving method for producing a rolled-up electrical or electronic component with many windings. The object is achieved by a method for producing a rolled-up component in which at least two functional and insulating layers, alternately arranged fully or partially over one another, are applied to a substrate with a sacrificial layer, wherein at least the functional or insulating layer that is arranged directly on the sacrificial layer has a perforation, at least on the two sides that are arranged substantially parallel to the rolling direction.
A method for producing a rolled-up component in which at least two functional and insulating layers alternately arranged fully or partially over one another are applied to a substrate having a sacrificial layer, wherein at least the functional or insulating layer that is arranged directly on the sacrificial layer comprises a perforation at least on the two sides that are arranged essentially parallel to the rolling direction.
The method according to claim I in which a substrate of silicon, silicon oxide, glass, ceramic, or a film of poly(ethylene terephthalate) (PET) or polyether ether ketone (PEEK), and a sacrificial layer of poly(vinyl alcohol) (PVA), poly(acrylic acid) (PAA), biopolysaccharides, cellulose acetate, poly(allylamine) (PAH), methylcellulose or ethylcellulose are used.
