摘要 |
There is described a semiconductor device having a storage node capacitor structure suitable for rendering memory cells compact, and storage nodes are prevented from tilting. The device includes a storage node which has a vertical surface extending in the direction perpendicular to the surface of a semiconductor substrate, and a dielectric film for tilt prevention purposes which is brought into close contact with the side surface of the vertical surface and which prevents the vertical surface from tilting.
