| titleOfInvention | Electrode foil, manufacturing method thereof and capacitor |
| abstract | An object of the present invention is to increase the capacity of a capacitor and reduce leakage current. In order to achieve this object, an electrode foil 2A according to the present invention comprises a base material 8 made of aluminum, a large number of recesses 9 formed on a surface 11 of the base material 8, and inner walls 12 of these recesses 9. And the dielectric film 3 formed on the surface 11 of the substrate 8, and the dielectric film 3 formed on the opening 10 of the recess 9 and the surface 11 of the substrate 8 is composed of zirconium oxide or hafnium oxide and aluminum oxide. The dielectric film 3 formed on the inner wall 12 of the recess 9 contains at least aluminum oxide, and the content of zirconium or hafnium in the dielectric film 3 is in the depth direction of the recess 9 from the opening 10 of the recess 9. It was supposed to decrease step by step. Accordingly, the present invention can realize an increase in the capacity of the capacitor 1 and a reduction in leakage current. [Selection] Figure 3 |
