Capacitors and method for manufacturing the same

摘要

A capacitor and a manufacturing method thereof with improved capacitance density, simplified production process, and/or improved high frequency characteristic without having to form a nano-scale pattern are provided. A capacitor element 12 includes a dielectric layer made of porous oxide substrate, first and second internal electrodes formed within holes of the porous oxide substrate, a first external electrode electrically connected to the first internal electrode, a second external electrode electrically connected to the second internal electrodes.

主权项

1. A substantially cuboid or substantially cubic capacitor including a plurality of cylindrical internal electrodes each having a positive or negative polarity and formed within holes of a porous dielectric material, the capacitor comprising:
a first external electrode layer formed on one main surface of the capacitor, the first external electrode layer electrically connected to more than one of said plurality of internal electrodes having one of positive or negative polarity, and the first external electrode layer being insulatingly pierced by more than one of said plurality of internal electrodes having the other of positive or negative polarity; an insulating layer formed on the first external electrode layer, the insulating layer being pierced by more than one of said plurality of internal electrodes having the other of positive or negative polarity; and a second external electrode layer formed on the insulating layer in parallel with the first external electrode layer, the second external electrode layer being electrically connected to said more than one of said plurality of internal electrodes having the other of positive or negative polarity.
