US Patent 7306822 - Ceramic nanopowder for forming passive electronic devices


This patent from Nanoproducts Corp. teaches forming passive electronics components such as capacitors, resistors, or inductors from ceramic nanoparticle films. Claim 1 reads:

1. A method for manufacturing a product comprising one or more passive electronic components, wherein the method comprises: providing ceramic nanopowders; suspending the nanopowders in a solvent thereby preparing a nanopowder dispersion or paste; forming a layer from the nanopowder dispersion or paste such that the average grain size of the nanopowder in the layer is equal to or less than 100 nanometers; and wherein the layer provides at least one passive electronic device function selected from the group consisting of capacitor, resistor, varistor and inductor; and processing the layer into one or more passive electronic components.
