Latest Patents

Jong-kook Song holds a patent for a trench isolation method of semiconductor devices. This method is designed to prevent the formation of a dent between a trench isolation region and an active region, as well as to avoid the generation of water spots during the cleaning process. The trench isolation method involves forming an undercut in a stress-relief oxide pad pattern located beneath a nitride layer pattern that defines an active region. A nitride liner, which serves as a stress-buffer layer, is then formed around the undercut to conform to its shape. This innovative approach ensures that even if the stress-buffer layer is partially etched during the removal of the nitride hard mask pattern, it remains intact above the substrate's upper surface. Additionally, the anti-reflection layer, which is a primary source of water spots, is simultaneously removed during the formation of the undercut.
