Abstract:
A method of manufacturing solid state capacitors comprising:providing an electrically conducting substrate; forming a plurality of porous bodies comprising valve action material on a surface of the substrate, the porous bodies each having an upper surface distal to the substrate; forming an electrically insulating layer over the porous bodies; forming a conducting cathode layer over the insulating layer; and dividing the substrate so as to make a plurality of capacitor-bodies, each capacitor-body comprising a porous-body-portion and a substrate-portion, said substrate-portion being a section of the electrically conducting substrate and said porous-body-portion comprising an electrically insulating layer and a conducting cathode layer, wherein an end region of each porous-body-portion distal from the substrate-portion is provided with a platform which is locally raised with respect to the rest of the end region, the platform providing a cathode terminal site and the substrate-portion providing an anode terminal site.
