Patents by Inventor Yoshihiro Okubo

Yoshihiro Okubo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Capacitor, capacitor device, electronic component, filter device, communication apparatus, and method of manufacturing capacitor device
    Patent number: 8320102
    Abstract: The present invention relates to a small, low-height capacitor device in which deterioration of characteristics such as leakage current is reduced. The capacitor device includes a supporting substrate 1; at least one capacitor element 21 disposed on the supporting substrate 1, including a dielectric layer 4 and a pair of electrodes 2 and 5 sandwiching the dielectric layer 4; and a sealant that seals the capacitor element 21 through a space 22. The dielectric layer 4 has an exposed part 23 exposed in the space 22. According to this structure, deterioration of the dielectric layer can be prevented, and a capacitor device exhibiting a good leakage current characteristic is obtained.
