METHOD FOR PRODUCING CAPACITOR, CAPACITOR, WIRING BOARD, ELECTRONIC DEVICE, AND IC CARD |
摘要 |
There is provided a method for producing a capacitor which is capable of producing a capacitor having a high withstand voltage and low leakage current, the method for producing a capacitor which is a method for producing a capacitor having a substrate serving as one electrode, a dielectric layer formed on top of the substrate, and the other electrode formed on top of the dielectric layer, the method including a step for forming an amorphous titanium oxide layer which is to become the dielectric layer on top of the substrate by anodizing the substrate, which is composed of titanium or titanium alloy, in an electrolyte solution containing hydrogen peroxide and having a temperature of 3° C. or less; and a step for forming the other electrode on top of the dielectric layer.
