The present invention concerns the field of solid state capacitors and the laying down of layers of material in the manufacture of such components. In particular aspects, the invention to a novel method for forming cathode material and protective barrier layers in solid state capacitors. According to one aspect of the invention there is provided a method of applying layers of material in the manufacture of electronic components, each layer being applied as a liquid precursor and then caused or allowed to solidify to form a solid layer, the method including the steps of: providing dispensing means for delivering precursor liquid, the dispensing means comprising a delivery head adapted to deliver precursor liquid from the dispensing means, providing mechanical transport means for moving the delivery head relative to a liquid delivery site, and for aligning the delivery head with the liquid delivery site, delivering one or more doses of liquid to the targeted delivery site in amounts suitable to form a layer of precursor material in a controlled amount at the desired location. Thus, in contrast to coating by dipping in a bulk liquid, components, or elements of components, may be coated in a manner which is targeted, selective and needs no more coating liquid than in necessary. By using the methods of the invention capacitors of improved performance may be obtained. |
