Abstract
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.
