Method of manufacturing semiconductor device |
| abstract |
A method of manufacturing a semiconductor device includes: forming a first film containing carbon over a silicon nitride film and a first conductive film; forming a first silicon oxide film surrounding the first film over the silicon nitride film and the first conductive film; removing the first film to form, in the first silicon oxide film, a first opening that exposes at least a part of the silicon nitride film and at least a part of the first conductive film; and forming a second conductive film on and in contact with the first conductive film in the first opening. |
