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.

Method for producing a rolled-up electrical or electronic component

The present invention relates to the area of micro- and nanoelectronics and relates to ultra-compact micro capacitors, how they can be used, for example, in electrical and electronic devices. The object of the present invention consists in specifying an ultra-compact micro capacitor with the highest capacity. The problem is solved by an ultra-compact micro capacitor which is made from a rolled-up layer stack of alternatingly arranged layers of dielectric and/or electrically insulating and electrically conductive materials with rolled-up lengths of the layer stack of at least 1 mm, and an absolute electrical storage capacity of at least 10 nF. The problem is additionally solved by a method, in which a layer containing a water-soluble cellulose derivative is applied to a substrate and a layer stack to same, the layer containing the cellulose derivative is removed from the substrate using water, an organic solvent and/or an organic solvent mixture, and the layer stack is rolled up with a rolling speed of more than 0.1 mm/min.
