Latest Patents

One of his latest patents is a method for producing an oxide superconductor. This method involves forming a layer of elements deficient in at least one of the components of the desired oxide superconductor on a substrate. The substrate is then immersed in a solution containing a supplementary element that is one of the deficient components. Another notable patent is a method of patterning a transparent conductor. This method focuses on forming a pattern of a transparent conducting film, such as indium tin oxide, on a substrate that includes silicon and is heated. A two-step etching method is employed, where the transparent conducting film is first wet-etched using an aqueous solution of a halogenide, followed by plasma etching of the interfacial reacted layer generated at the interface.
