Abstract: A method of forming a semiconductor device includes the following processes. A dummy insulating film is formed over a semiconductor substrate by using a source material that is free of carbon as an essential component. A hole that penetrates the dummy insulating film is formed. A conductive film is formed, which covers at least a side wall of the hole of the dummy insulating film. The dummy insulating film is removed to expose an outer surface of the conductive film.

Abstract: A semiconductor device includes a memory cell area; and a peripheral circuit area separated by a groove from the memory cell area. The peripheral circuit area is positioned outside the memory cell area. The memory cell area includes a plurality of electrodes that stand; and a first insulating film that support the plurality of electrodes standing. The first insulating film has a plurality of holes through which the plurality of electrodes penetrates. The first insulating film is in contact with at least a part of an outside surface of the electrode. The first insulating film has at least a first opening which is connected to part of the plurality of holes. The first insulating film has at least a second opening which is closer to the groove than any holes of the plurality of holes. The second opening is separated from the plurality of holes.

Abstract: A method of manufacturing a semiconductor device includes: (A) forming a gate electrode of a transistor on a substrate, a top layer of the gate electrode being a first metal film; (B) blanket depositing an interlayer insulating film; and (C) forming a first contact hole contacting the gate electrode and a second contact hole contacting a surface of the substrate. The method further includes: (D) siliciding an exposed surface of the first metal film to form a first silicide at a bottom of the first contact hole; (E) after the (D) process, blanket depositing a second metal film; and (F) after the (E) process, forming a second silicide at a bottom of the second contact hole through a silicide reaction between the second metal film and the surface of the substrate.
