Latest Patents

One of Ryo Kubota's latest patents involves a semiconductor device and a method of manufacturing the same. This patent describes a process where a hole is formed through a first insulating film and an insulating interlayer stacked over a semiconductor substrate. The method allows for side-etching of the inner wall of the hole, specifically in a portion of the insulating interlayer. This results in a structure where the first insulating film projects out from the edge towards the center of the hole. The process continues with the formation of a lower electrode film that extends over the top surface, side face, and back surface of the first insulating film, as well as over the inner wall and bottom surface of the hole. A protective film is then filled in the hole, followed by the removal of the lower electrode film in specific portions. Finally, the protective film is removed, and a cylindrical capacitor is formed in the hole.
