Abstract: An intermediate product for producing a nanoelectronic component structure and a nanoelectronic component structure, each have a substrate, a cavity formed therein, and a nanostructure which partly spans the cavity. A method for producing a nanoelectronic component structure, includes the steps of introducing a cavity into the substrate, and each cavity is bridged by at least one nanostructure. This allows mechanical stress states in nanostructures to be adjusted in a decoupled manner from location and direction. This is achieved in that the nanoelectronic component structure has an arm, which partly overlaps with the cavity, on one side of the respective cavity, the arm being bent or shrunk at the arm end protruding beyond or into the respective cavity. A gap is formed over the cavity, and the nanostructure is arranged on the respective arm so as to span the respective gap and is fixed between the respective arm and contact electrodes formed on each side of the gap.

Abstract: A roll-up type capacitor having at least one cylindrical part, a first external electrode on one end of the cylindrical part and a second external electrode on another end of the cylindrical part. The cylindrical part is formed by rolling-up a lower electrode layer and an upper electrode layer with at least a dielectric layer sandwiched therebetween. The first external electrode is electrically connected to the upper electrode layer, and the second external electrode is electrically connected to the lower electrode layer. A thickness of the upper electrode layer at a part where it is connected to the first external electrode is larger than a thickness of the other part of the upper electrode layer, and/or a thickness of the lower electrode layer at a part where it is connected to the second external electrode is larger than a thickness of the other part of the lower electrode layer.
