Abstract
The present invention concerns the field of solid state capacitors and relates particularly to massed production methods for manufacturing solid state capacitors. According to one aspect of the present invention there is provided a method of manufacturing multiple solid state capacitors comprising: providing a metal substrate layer (10); forming on an upper surface of the substrate layer a plurality of upstanding bodies (16) 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 (27, 21) by liquid or vapour phase deposition or by 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, encapsulating side walls of each body with an electrically insulating material (24); 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 (23) and a cathode terminal surface portion at the other end consisting of exposed intermediary layer (21).
