Latest Patents

One of his latest patents is titled "Method of producing inorganic nanoparticles in atmosphere and device therefor." This invention provides a method and device for producing nanoparticles of low melting point materials, such as gold, at a rate more than ten times faster than conventional technology. The process maintains a low enough temperature to avoid damaging heat-sensitive materials downstream. The method involves inserting a wire made of a low melting point inorganic material into a plasma-generating capillary tube or nozzle, where atmospheric-pressure high-frequency plasma is generated. The plasma is created by applying a high-frequency voltage with a specific waveform that maximizes its value during the rise and immediately falls, pulse-modulated to a duty ratio of 10% or less.

Another significant patent is the "Method of fabricating thin film by microplasma processing and apparatus for same." This invention allows for the fabrication of thin films of metals or metallic compounds on high-melting-point substrates, such as silicon or ceramics, without the need for harmful gases. The method utilizes atmospheric-pressure plasma as both a reaction field and a heat source, ensuring satisfactory adhesion of the thin film. The process involves heating and evaporating the raw material while maintaining the flow rate and temperature of the plasma gas, followed by spraying the evaporated material onto the substrate.
