Latest Patents
Iwamoto holds two notable patents that showcase his expertise. The first patent details a sputtering target for producing electroconductive transparent films, comprising indium oxide and tin oxide. This invention is designed with a unique shape that ensures that at least 80% by weight of the target is present in an erosion area during the sputtering process. The process for manufacturing this sputtering target involves molding a slurry or a powder mixture of indium oxide and tin oxide into a desired shape and sintering it to finalize the product.
The second patent pertains to an indium oxide or indium oxide/tin oxide powder, characterized by a narrow average primary particle diameter ranging from 1 to 0.01 micrometers. This powder features a BET surface area of 15 to 50 m²/g and a specific surface area of 2 to 5 m²/g, determined from the particle size distribution. The mixed powder is produced by coprecipitating indium- and tin-containing salts from a solution, followed by calcining and pulverizing the result using a specialized vibrating pulverizer. The resultant sintered body boasts a density of at least 5.3 g/cm³, a specific resistance ranging from 2×10⁻³ to 2×10⁻⁴ Ω·cm, and an average grain diameter between 5 to 15 micrometers.
