Title: Koji Itoh: Innovator in Polyimide Technology
Introduction
Koji Itoh is a prominent inventor based in Otsu, Japan. He has made significant contributions to the field of polyimide technology, holding a total of 2 patents. His work focuses on enhancing the properties of electronic components through innovative materials and processes.
Latest Patents
Koji Itoh's latest patents include a polyimide resin precursor solution and laminates for electronic components made using this solution. The process involves applying a polyimide resin precursor solution containing a palladium compound on a polyimide substrate. After drying the coating, the layer is irradiated with ultraviolet rays in the presence of a hydrogen donor to form nuclei for primer plating. This is followed by forming a metal primer layer through electroless plating. The polyimide resin precursor layer is then converted into a polyimide resin layer through imidation by heating. This invention significantly improves adhesion to metal layers while maintaining the inherent characteristics of the substrate and providing excellent insulating properties.
Another notable patent involves a resin etching solution and a process for etching polyimide resins. This solution contains a hydroxyalkylamine, an alkali metal compound, and water, or an aliphatic alcohol, an aliphatic amine, an alkali metal compound, and water. The process is designed for etching a polyimide film that has a resist pattern or metal layer pattern formed on either or both sides.
