Abstract:
A method of manufacturing multiple solid state capacitors comprising:providing a metal substrate layer; forming on an upper surface of the substrate layer a plurality of upstanding anode consisting of porous sintered valve-action metal; forming a dielectric layer on the bodies; forming a cathode layer on the dielectric layer; coating a top end of each upstanding body with at least one conducting intermediary layer by liquid or vapor phase deposition or by the application of an immobilized flowable composition such as a solidifiable paste, thereby to form an intimate physical contact between the cathode layer and the intermediate layer; juxtaposing a solid lid on the respective top ends of the anode bodies; encapsulating side walls of each body with an electrically insulating material; removing the solid lid from the respective top ends of the encapsulated anode bodies; and dividing the processed substrate into a plurality of individual capacitor bodies each having a sleeve of encapsulating material, an anode terminal surface portion at one end consisting of exposed substrate and a cathode terminal surface portion at the other end consisting of exposed intermediary layer.
