Latest Patents

Nobutaka Nagai's latest patents include a groundbreaking semiconductor device and method of manufacturing the same. This invention involves forming a hole that extends through a first insulating film and an insulating interlayer stacked over a semiconductor substrate. The process allows for side-etching of the inner wall of the hole, specifically in a portion of the insulating interlayer. This technique results in a structure where the first insulating film projects out from the edge towards the center of the hole. The method further includes forming 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. After filling a protective film in the hole, the lower electrode film is selectively removed from specific portions, followed by the removal of the protective film, ultimately leading to the formation of a cylindrical capacitor within the hole.
