Latest Patents

Higashi's latest patents include a "Transparent Electrode Forming Apparatus and Method of Fabricating Active Matrix Substrate." This invention describes an active matrix substrate that features a line layer made of an Al-based metal, with parts exposed through a contact hole in an insulating film. The pixel electrodes are formed from an ITO film on the insulating film, and a jumper line connects a disconnected portion of a protect ring. This innovative approach reduces the number of fabrication steps required. His second patent, "Method of Manufacturing Thin Film Transistor Panel Having Protective Film of Channel Region," focuses on creating a protective film for the channel region of a thin film transistor. This method ensures that even if defects occur in the semiconductor film, pinholes do not form in the gate insulating film, maintaining the breakdown voltage.
