Elektronische keramische Vorrichtung und Verfahren zur Herstellung

摘要

For minimizing the size of a ceramic electronic device for elimination of noise in a digital circuit installed in an electric apparatus, a method comprises the steps of placing a ceramic layers structure encapsulating internal electrodes on a substrate which has a plurality of apertures arranged therein, making through holes in the ceramic layers structure by applying a sand blasting through the apertures of the substrate, and forming in the through holes external electrodes connected to the internal electrodes.
