Title: Naoyuki Tsukamoto: Innovator in Film Formation Technology
Introduction
Naoyuki Tsukamoto is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of film formation technology, holding a total of 3 patents. His innovative methods focus on enhancing mass productivity and efficiency in the creation of metal oxide films.
Latest Patents
Tsukamoto's latest patents include a film formation method that boasts excellent mass productivity. This method significantly reduces the time required to form a film with a desired thickness. The process involves atomizing or dropletizing a liquid containing a metal complex, which serves as the raw material solution. The resulting mist or droplets are then conveyed to a base using a carrier gas, where a metal oxide film is formed through thermal reaction. The metal oxide film comprises a crystalline oxide semiconductor, utilizing a metal complex that exhibits an exothermic peak at temperatures between 480° C. and 520° C. during thermogravimetric-differential thermal analysis.
Another notable patent by Tsukamoto describes a similar film formation method that also emphasizes mass productivity. This method employs one or multiple aqueous solutions containing at least one metal complex with two or more different ligands, as well as a gallium compound. The process includes atomizing or dropletizing the solutions, conveying the mist or droplets to a base, and thermally reacting them to form a metal oxide film.
