摘要：The present invention relates to the field of solid state capacitors. The presentinvention seeks to provide improved capacitors and improved methods of manufacturingsuch capacitors. According to one aspect of the present invention there is provided amethod of manufacturing solid state capacitors comprising: providing an electricallyconducting substrate (109); forming a plurality of porous bodies (105) comprising valveaction material on a surface of the substrate, the bodies each having an upper surfacedistal to the substrate; forming an electrically insulating layer over the bodies; forming aconducting cathode layer over the insulating layer applied to the bodies; and dividing thesubstrate into capacitor portions, each portion comprising a body and a portion ofsubstrate, characterised in that an end region of each body portion distal from thesubstrate is provided with a platform (106) which is locally raised with respect to the restof the end region, the platform providing a cathode terminal site in the final capacitor,and the substrate portion providing an anode site.
