Title: Klyoshi Ogata: Innovator in Thin Film Transistor Technology
Introduction
Klyoshi Ogata is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of thin film transistors, holding 2 patents that showcase his innovative approach to manufacturing processes.
Latest Patents
Ogata's latest patents include a process for manufacturing thin film transistors on unannealed glass substrates. This innovative method utilizes inexpensive, unannealed glass as a substrate. The process involves oxidizing the surface of a polycrystalline silicon film doped with boron or phosphorus using ozone at a processing temperature of 500°C or below. This treatment forms a silicon oxide film of 4 to 20 nm thick on the surface of polycrystalline silicon. As a result, the level density at the interface between the gate-insulating layer and the channel layer can be reduced, allowing for the formation of thin-film transistors with less variation in characteristics on unannealed glass substrates.
Another notable patent by Ogata is related to the thin film transistor and the method for manufacturing the same. Similar to his previous patent, this invention also employs inexpensive, unannealed glass as a substrate and follows the same oxidation process to achieve improved transistor performance.
