Latest Patents

One of Nakano's latest patents is a method for producing solid electrolytic capacitors that can be directly connected to semiconductor components. This innovative method offers superior high-frequency characteristics. The process involves making one surface of an aluminum foil porous, forming a dielectric layer on the porous portion, and providing a through hole at a specific location. An insulation layer covers the non-porous surface and the inner wall of the through hole, while a solid electrolytic layer is applied on the dielectric layer. A through hole electrode is formed, and a collector layer is added on top of the solid electrolytic layer. The insulation layer has an opening for a connection terminal, which connects to the exposed surface of the through hole electrode.

Another patent by Nakano details a method for manufacturing solid electrolytic capacitors that can be mounted directly on semiconductor components. This method also emphasizes high-frequency characteristics. The process begins with an aluminum foil that has a resist film and a through hole. An insulation film is formed to cover the other surface and fill the first through hole. After removing the resist film, the aluminum foil surface is roughened to allow for a dielectric layer. A second through hole is created in the insulation film, and a through hole electrode is formed. Finally, a solid electrolytic layer and a collector layer are added, along with connection terminals.
