A method for manufacturing a superconducting LC-type resonator of the type including at least one high-resistivity substrate on which are printed an inductive meander, a first so-called lower electrode and a second so-called upper electrode arranged opposite the first so as to form together a capacitor connected in parallel with the inductive meander, as well as inductive coupling means dedicated to the resonator, in which a sacrificial aluminium layer is deposited between the first and second electrodes. Also disclosed is the superconducting LC-type resonator thus obtained and the use of such a resonator for detecting the noise of a millimetre photon.

An electrode holder and a method for producing an electrode for an aluminum electrolytic capacitor are provided that enable prevention of exfoliation of a porous layer during chemical formation even when the porous layer is formed on an aluminum electrode so as to have a thickness of 200 micrometers or greater. When an aluminum electrode 10 having at least one surface 11 on which a porous layer 17 having a thickness of 200 micrometers or greater is formed is subjected to chemical formation in a chemical formation solution, the aluminum electrode 10 is held by an electrode holder 50. The electrode holder 50 includes: an insulating first support plate 51 configured to overlap the one surface 11 of the aluminum electrode 10; an insulating second support plate 52 configured to overlap the other surface 12 of the aluminum electrode 10; and a connecting part 53 configured to connect the first support plate 51 and the second support plate 52 to each other. A portion of the first support plate 51 that overlaps the porous layer 17 while being in contact therewith is formed with a porous member 510.

The electrode manufacturing system comprises a cutting device. The cutting device cuts an electrode material along one direction of the electrode material to manufacture electrodes. The electrode material comprises first sections and a second section. The first section includes an active material doped with alkali metal, and extends in the one direction. The second section is located between two adjacent first sections of the first sections. In the second section, the active material doped with alkali metal is absent. The cutting device cuts the second section.

A method for manufacturing a high-profile capacitor with high capacity includes providing a substrate, forming a first mold layer, a first supporter layer, a second mold layer, and a second supporter layer on the substrate, where at least one of the first mold layer and the second mold layer are made of a dielectric material having a low or super low dielectric constant, defining at least one contact hole, where the now-surrounding first and second supporter layers reinforce the at least one contact hole and form first and second supporter patterns respectively, forming a lower electrode on an inner surface of the at least one contact hole, and removing the first mold layer and/or the second mold layer being made of the dielectric material by ashing.

A multilayer ceramic electronic component includes a multilayer body including two major surfaces opposite to each other in a layer stacking direction, two side surfaces opposite to each other in a widthwise direction orthogonal or substantially orthogonal to the layer stacking direction, and two end surfaces opposite to each other in a lengthwise direction orthogonal or substantially orthogonal to the layer stacking direction and the widthwise direction, and external electrodes provided on the two end surfaces.
