Latest Patents
Fujii holds a notable patent titled "Method for producing In₂O₃–SnO₂ precursor sol." This innovative invention pertains to a technique for forming a transparent conductive thin film comprising indium oxide and tin oxide on plastic substrates that have lower heat resistance than glass or ceramics. The process involves hydrolyzing and polymerizing a solution that includes indium and tin alkoxides, specifically using tri-s-butoxyindium or tri-t-butoxyindium as the indium source. A critical aspect of this method is the temperature-controlled addition of water to the alkoxide solution at temperatures not exceeding -20°C. Following the creation of the In₂O₃–SnO₂ precursor sol, it can be applied to a substrate to form a gel film, which is then crystallized through ultraviolet and laser beam irradiation to produce a conductive thin film.
