Patent ID: 8422200

Claim:
A solid capacitor having an embedded electrode, comprising: a substrate unit including at least one substrate body and a conductive body embedded into the at least one substrate body, wherein the at least one substrate body has at least one lateral opening and a plurality of top openings, and the conductive body has at least one lateral conductive area exposed from the at least one lateral opening and a plurality of top conductive areas respectively exposed from the top openings; a first conductive unit including a plurality of first conductive layers separated from each other and formed on the at least one substrate body to respectively cover the top conductive areas; a second conductive unit including at least one second conductive layer formed on the at least one substrate body to cover the first conductive layers, wherein the at least one second conductive layer has a porosity rate larger than that of each first conductive layer; a first insulative unit including at least one first insulative layer covering the outer surface of the at least one second conductive layer; a third conductive unit including at least one third conductive layer covering the at least one first insulative layer; a second insulative unit including at least one second insulative layer covering one part of the outer surface of the at least one third conductive layer, wherein the substrate unit, the first conductive unit, the second conductive unit, the first insulative unit, the third conductive unit, and the second insulative unit are combined to form a core unit; and an end electrode unit including at least two end electrode conductive bodies respectively covering two opposite end portions of the core unit, wherein one of the at least two end electrode conductive bodies contacts the at least one lateral conductive area, and the other end electrode conductive body contacts the other part of the outer surface of the at least one third conductive layer.
